Compassion

A young man said to the abbot from the monastery, “I’d actually like to be a monk, but I haven’t learned anything in life. All my father taught me was to play chess, which does not lead to enlightenment. 

The abbot asked for a chessboard, sent for a monk, and told him to play with the young man.

But before the game began, he added, “Although we need diversion, we cannot allow everyone to play chess the whole time. So, we have the best players here; if our monk loses, he will leave the monastery and his place will be yours.”

The abbot was serious. The young man knew he was playing for his life, and broke into a cold sweat; the chessboard became the center of the world.

The monk began badly. The young man attacked, but then saw the saintly look on the other man’s face; at that moment, he began playing badly on purpose. After all, a monk is far more useful to the world.

Suddenly, the abbot threw the chessboard to the floor.

“You have learned far more than was taught you,” he said. “You concentrated yourself enough to win, were capable of fighting for your desire. Then, you had compassion and were willing to make a sacrifice in the name of a noble cause. Welcome to the monastery, because you can balance discipline with compassion.”

Eternal Companion

A ticket collector in a train found an old worn out wallet in a compartment full of many people. He looked inside to find the name of its owner. There was no clue. All that there was in it, was some money and a picture of Bhagwan Sri Krishna. He held it up and asked, 'Who does this wallet belong to?'

An old man said, 'That's my wallet, please give it to me.' The ticket collector said, 'You'll have to prove that it is yours. Only then I can hand it over to you.' 

The old man smiled a toothless smile and said. 'It has a picture of Sri Krishna in it.' 

The ticket collector said, 'That is no proof; anyone can have a picture of Sri Krishna in his wallet. What is special about that? Why is your picture not there in it?'

The old man took a deep breath and said, 'Let me tell you why my picture is not there in it. My father gave this wallet to me when I was in school. I used to get a small sum as pocket money then. I had kept a picture of my parents in it.

When I was a teenager I was greatly enamoured by my good looks. I removed my parent's picture and put in, one of my own. I loved to see my own face and my thick black hair. 

Some years later, I got married. My wife was very beautiful and I loved her a lot. I replaced my own picture in this wallet with a picture of her. I spent hours gazing at her pretty face.

When my first child was born, my life started a new chapter. I shortened my working hours, to play with my baby. I went late to work and returned home early too. Obviously, my baby's picture occupied the prized position in my wallet.'

The old man's eyes brimmed with tears as he went on.. 'My parents passed away many years ago. Last year my wife too left her mortal coil. My son, my only son is too busy with his family. He has no time to look after me. All that I had ever held close to my heart is far, far away from my reach now.

Now I have put this picture of Bhagwan Sri Krishna in my wallet. It is only now that I have realized that He is the eternal companion. He will never leave me. Alas! If only I had realized this before. If only I had loved the Lord Krishna all these years, with the same intensity as I loved my family, I would not have been so lonely today!'

The collector quietly gave the wallet to the old man. When the train stopped at the next station, the ticket collector went to the book stall at the platform and asked the salesman,

'Please give me a small picture of Sri Krishna I need one to put in my wallet!'

Adversity

A young woman went to her mother and told her about her life and how things were so hard for her. She did not know how she was going to make it and wanted to give up. She was tired of fighting and struggling. It seemed as when one problem was solved, a new one arose.

Her mother took her to the kitchen. She filled three pots with water and placed each on a high fire. Soon the pots came to boil. In the first she placed carrots, in the second she placed eggs, and in the last she placed ground coffee beans.

She let them sit and boil; without saying a word. In about twenty minutes she turned off the burners. She fished the carrots out and placed them in a bowl. She pulled the eggs out and placed them in a bowl. Then she ladled the coffee out and placed it in a bowl. Turning to her daughter, she asked, “Tell me what you see.”

“Carrots, eggs, and coffee,” she replied.

Her mother brought her closer and asked her to feel the carrots. She did and noted that they were soft. The mother then asked the daughter to take an egg and break it. After pulling off the shell, she observed the hard boiled egg. Finally, the mother asked the daughter to sip the coffee. The daughter smiled as she tasted its rich aroma. The daughter then asked, “What does it mean, mother?”

Her mother explained that each of these objects had faced the same adversity: boiling water. Each reacted differently. The carrot went in strong, hard, and unrelenting. However, after being subjected to the boiling water, it softened and became weak.

The egg had been fragile. Its thin outer shell had protected its liquid interior, but after sitting through the boiling water, its inside became hardened.

However, the ground coffee beans were unique. After they were in the boiling water, they had changed the water. “Which are you?” she asked her daughter.

When adversity knocks on your door, how do you respond? Are you a carrot, an egg, or a coffee bean?

Think of this: Which am I?

Am I the carrot that seems strong, but with pain and adversity do I wilt and become soft and lose my strength?

Am I the egg that starts with a malleable heart, but changes with the heat? Did I have a fluid spirit, but after a death, a breakup, a financial hardship or some other trial, have I become hardened and stiff? Does my shell look the same, but on the inside am I bitter and tough with a stiff spirit and hardened heart?

Or am I like the coffee bean? The bean actually changes the hot water, the very circumstance that brings the pain. When the water gets hot, it releases the fragrance and flavor.

If you are like the bean, when things are at their worst, you get better and change the situation around you. When the hour is the darkest and trials are their greatest do you elevate yourself to another level?

How do you handle adversity?
Are you a carrot, an egg or a coffee bean?

Honesty

A successful business man was growing old and knew it was time to choose a successor to take over the business.

Instead of choosing one of his Directors or his children, he decided to do something different. He called all the young executives in his company together.

He said, “It is time for me to step down and choose the next CEO. I have decided to choose one of you.”

The young executives were shocked, but the boss continued. “I am going to give each one of you a SEED today – one very special SEED. I want you to plant the seed, water it, and come back here one year from today with what you have grown from the seed I have given you. I will then judge the plants that you bring, and the one I choose will be the next CEO.”

One man, named Jim, was there that day and he, like the others, received a seed. He went home and excitedly, told his wife the story. She helped him get a pot, soil and compost and he planted the seed.

Everyday, he would water it and watch to see if it had grown. After about three weeks, some of the other executives began to talk about their seeds and the plants that were beginning to grow.

Jim kept checking his seed, but nothing ever grew. Three weeks, four weeks, five weeks went by, still nothing. By now, others were talking about their plants, but Jim didn’t have a plant and he felt like a failure.

Six months went by — still nothing in Jim’s pot. He just knew he had killed his seed. Everyone else had trees and tall plants, but he had nothing. Jim didn’t say anything to his colleagues, however… He just kept watering and fertilizing the soil – He so wanted the seed to grow.

A year finally went by and all the young executives of the company brought their plants to the CEO for inspection.

Jim told his wife that he wasn’t going to take an empty pot. But she asked him to be honest about what happened. Jim felt sick to his stomach, it was going to be the most embarrassing moment of his life, but he knew his wife was right.

He took his empty pot to the board room. When Jim arrived, he was amazed at the variety of plants grown by the other executives. They were beautiful — in all shapes and sizes.

Jim put his empty pot on the floor and many of his colleagues laughed, a few felt sorry for him!

When the CEO arrived, he surveyed the room and greeted his young executives.

Jim just tried to hide in the back. “My, what great plants, trees, and flowers you have grown,” said the CEO. “Today one of you will be appointed the next CEO!”

All of a sudden, the CEO spotted Jim at the back of the room with his empty pot. He ordered the Financial Director to bring him to the front.

Jim was terrified. He thought, “The CEO knows I’m a failure! Maybe he will have me fired!”

When Jim got to the front, the CEO asked him what had happened to his seed – Jim told him the story.

The CEO asked everyone to sit down except Jim. He looked at Jim, and then announced to the young executives, “Behold your next Chief Executive Officer! His name is Jim!”

Jim couldn’t believe it. Jim couldn’t even grow his seed.

“How could he be the new CEO?” the others said.

Then the CEO said, “One year ago today, I gave everyone in this room a seed. I told you to take the seed, plant it, water it, and bring it back to me today. But I gave you all boiled seeds; they were dead – it was not possible for them to grow. All of you, except Jim, have brought me trees and plants and flowers. When you found that the seed would not grow, you substituted another seed for the one I gave you. Jim was the only one with the courage and honesty to bring me a pot with my seed in it. Therefore, he is the one who will be the new Chief Executive Officer!”

* If you plant honesty, you will reap trust.
* If you plant goodness, you will reap friends.
* If you plant humility, you will reap greatness.
* If you plant perseverance, you will reap contentment.
* If you plant consideration, you will reap perspective.
* If you plant hard work, you will reap success.
* If you plant forgiveness, you will reap reconciliation.
* If you plant faith in God , you will reap a harvest.

So, be careful what you plant now; it will determine what you will reap later..

“Whatever You Give To Life, Life Gives You Back”

Important things in life

A philosophy professor stood before his class with some items on the table in front of him. When the class began, wordlessly he picked up a very large and empty mayonnaise jar and proceeded to fill it with rocks, about 2 inches in diameter.

He then asked the students if the jar was full. They agreed that it was.

So the professor then picked up a box of pebbles and poured them into the jar. He shook the jar lightly. The pebbles, of course, rolled into the open areas between the rocks.

He then asked the students again if the jar was full. They agreed it was.

The professor picked up a box of sand and poured it into the jar. Of course, the sand filled up everything else.

He then asked once more if the jar was full. The students responded with a unanimous “Yes.”

“Now,” said the professor, “I want you to recognize that this jar represents your life. The rocks are the important things – your family, your partner, your health, your children – things that if everything else was lost and only they remained, your life would still be full.

The pebbles are the other things that matter – like your job, your house, your car.

The sand is everything else. The small stuff.”

“If you put the sand into the jar first,” he continued “there is no room for the pebbles or the rocks. The same goes for your life.

If you spend all your time and energy on the small stuff, you will never have room for the things that are important to you. Pay attention to the things that are critical to your happiness. Play with your children. Take your partner out dancing. There will always be time to go to work, clean the house, give a dinner party and fix the disposal.

Take care of the rocks first – the things that really matter. Set your priorities. The rest is just sand.”

Ramayana in short

Lord Brahma went on to describe the famous tale of Ramayana . He began by giving the details of Sri Ram's lineage and said-' I (Lord Brahma) manifested from the Lotus originating from the navel of Lord Vishnu. Sage Marich manifested from me while Kashyap was Marich's son. Surya manifested from Kashyap, Vaivaswat-Manu from Surya and Ikshavaku was born to Vaivaswat-Manu. The great King Raghu was also the descendant of Ikshavaku. Raghu's son was Aja, whose son was Dasharath.

Dasharath had three queens-Kaushalya, Kaikeyi and Sumitra. Kaushalya gave birth to Sri Ram while Kaikeyi was the mother of Bharat. Sumitra had two sons-Laxman and Shatrughan.

Sri Ram had great devotion towards his parents. Sage Vishwamitra, who was tormented by the demons, took Sri Ram and Laxman along with him so that he could do his penance peacefully. He assured Dashrath that he would make both his sons proficient in all the scriptures as well as in the usage of various weapons. With great reluctance, Dasharath allowed Sri Ram and Laxman to go along with Vishwamitra.

Once in the forest Sri Ram assured his Guru to do his penance without bothering about the demons. Vishwamitra commenced his penance and Sri Ram killed all the demons trying to disturb him. The names of few demons killed by Sri Ram were Tadaka, Subahu, etc.

Janak, the father of Sita had organized a grand 'Swayamvar' ceremony to which he had invited all the prominent kings of that time. He had also sent invitation to Vishwamitra. Vishwamitra set out for Janakpur accompanied by Sri Ram and Laxman.

Janak had a huge bow gifted to him by Lord Shiva and which he worshipped daily with appropriate ritual. Once during the process of cleaning the area where Shiva's bow was kept, Sita lifted the bow and kept it a distance. Later on she forgot to keep it back at the original place. When Janak came to worship the bow he was surprised to find it to be kept at a different place. He made an inquiry and Sita confessed that she had kept it while cleaning the place of worship. Janak just could not believe that his tender looking daughter possessed such strength and power. No wonder he decided to give Sita's hand in marriage to such a man who could break Shiva's bow. So, he made a declaration that anybody capable of breaking Shiva's bow could have Sita as his wife.

There were many mighty warriors present at the 'Swayamvar' ceremony but none had the strength to even lift the bow what to say about breaking it. Finally, as the destiny would have liked it, Sri Ram broke the bow into three pieces and thus married Sita. Laxman married Urmila- another daughter of Dasharath while Bharat and Shatrughan married Mandavi and Keertimayi respectively, both daughters of King Kushadhwaja.

Later on, when Dasharath decided to crown Sri Ram as the King of Ayodhya, Kaikeyi played a spoilsport and demanded her son-Bharat to be made the King of Ayodhya and Sri Ram to be sent into exile for fourteen years. Actually, Kaikeyi had taken undue advantage of Dasharath's helpless condition to serve her own interest. Once, Dasharath was busy fighting a battle oblivious of the fact that one of the wheels of the chariot was about to eject from its axle as the nail supporting it had fallen off. Kaikeyi, who was also accompanying him, saved his life by preventing the wheel from falling off and thus maintaining the balance of the chariot. When Dasharath learnt how Kaikeyi had saved his life he promised to grant her two boons. At that time Kaikeyi did not ask for any thing and merely said that she would demand at the appropriate time. So, when the time for Ram's coronation came she thought it was the best opportunity for her to remind Dasharath about the two boons he had promised to grant her.

Dasharath, bound by his deep love for Sri Ram on the one hand and by his vow on the other, agreed to Kaikeyi's demand with a heavy heart. Sri Ram without any hesitation followed his father's order and left for the forest. How could have Sita and Laxman lived without him? So, they too accompanied him to the forest. In course of his journey, Sri Ram passed by many holy places and finally after reaching Chitrakoot he made a 'Parna kuti' (hermitage made of leaves) and started living there.

The shock caused by Sri Ram's separation proved to be fatal for Dasharath, who died with an unfulfilled desire of having a glimpse of his dearest son. Bharat, who at that time was at his maternal uncle's place, returned to Ayodhya after hearing the news of his father's demise and performed his last rites. He then went to Chitrakoot and tried his level best to convince Sri Ram into returning back to Ayodhya. But, Sri Ram did not agree, as it was against his principle to disobey the commands of his father. Sri Ram gave his pair of wooden sandals to Bharat as a token of love and requested him to return to Ayodhya. Bharat returned to Ayodhya and kept Sri Ram's sandals on the throne. He then stationed himself at Nandigram- a city situated at the outskirts of Ayodhya and started ruling from there on behalf of his elder brother. He had vowed not to return to Ayodhya till the completion of Sri Ram's period of exile.

From Chitrakoot, Sri Ram reached Dandakaranya accompanied by Sita and Laxman and started living in a hermitage made of leaves. There they also met prominent sages like Atri and Agastya. Once an ogress named 'Surpanakha' (Ravan's sister) attacked Sri Ram but Laxman retaliated by severing both her ears as well as her nose. Surpanakha, badly injured and bleeding profusely, went to Khardushan and narrated her woeful tale. Khardushan attacked Sri Ram with a huge army consisting of fourteen thousand soldiers but lost all his men in the battle.

The revengeful Ravan went to the hermitage disguised as a hermit and abducted Sita while Sri Ram was away in pursuit of Marich-the golden deer. Actually, Marich was a demon, who had disguised himself as a golden deer on the instruction of Ravan so that Sita could be abducted successfully. Ravan knew quite well that it was impossible for him to abduct Sita in the presence of Sri Ram. So, he hatched a plan according to which Marich was to disguise himself as a golden deer and enchant Sita. Ravan was sure that Sita after being enchanted by the beauty of the golden Deer would ask her husband to get it at any cost. Everything happened as per the plan of Ravan and he was successful in abducting Sita.

When Sri Ram did not find Sita in the hermitage he became worried and started searching for her frantically. On the way he met old Jatayu, who had got injured while trying to resist Ravan from taking away Sita. Jatayu informed him that Ravan had taken Sita towards south. Jatayu was so badly injured that he died soon after giving Sita's information to Sri Ram. Sri Ram performed his last rites and continued with his search. He proceeded towards south as per the instructions of Jatayu and reached 'Rishyamook' mountain where he met Sugreeva, whom he befriended. He killed Bali, who harboured enemity against his brother- Sugreeva. He then made Sugreeva the King of 'Kishkindha' and himself went to live at 'Rishyamook' mountain.

Sugreeva sent monkeys in all directions to find out Sita's whereabouts. Hanuman went towards south and with the help of Sampati managed to find out the exact location where Ravan had kept Sita. Hanuman took a giant leap and the next moment he found himself on the other side of the ocean. He went to 'Ashok- Vatika' where Ravan had kept Sita in captivity. He presented the ring to her, which Sri Ram had given him. Sita, in turn gave her 'Chudamani'(ornament) and requested him to give it to Sri Ram. Jumping from one branch to another, hungry Hanuman ate all the fruits and in the process destroyed the beautiful garden. When Ravan came to know about the destruction caused in the beautiful garden of 'Ashok Vatika', he sent many demons to capture Hanuman. But, all of them were killed including Akshay Kumar, Ravan's son. Ultimately, Hanuman was made captive by Meghanad and produced before Ravan, who ordered his tail to be set ablaze as a punishment. Hanuman, with his tail ablaze, jumped from one palace to another and burnt the golden city of Lanka within no time. He then returned to his master Sri Ram and described everything in detail.

Finally, Sri Ram attacked Lanka with a huge army comprising of mighty warriors like Hanuman, Sugreeva, Angad and many others. A fierce battle took place in which all the demons including Ravan were killed. The victorious Sri Ram returned to Ayodhya along with his consort Sita. The residents of Ayodhya danced in joy at the return of their prodigious son. Sri Ram ruled over Ayodhya for eleven thousand years. Finally he ascended to the heaven taking along all the people of Ayodhya with him but before doing that he appointed Lav and Kush-his Sons, as his successors.

Kindness

Rantideva who was a king, became a hermit in the forest. He had given his wealth to the poor and lived a simple life in the solitude of the jungle. He and his family had only the bare necessities of life.

One day, after a fast of forty-eight hours, a light meal of rice with milk and sugar was prepared for him.

A poor Brahmin came up to the door of the hut and asked for food. Rantideva gave him half of his rice. Then came a Sudra begging for help and Rantideva gave him half of what remained.


Then he heard a dog barking; the poor beast seemed to be starving. Rantideva gave him what was left. Last of all came a Pariah who stopped at the hermit's door and asked for help. Rantideva gave him the milk and the sugar, and continued to fast.


Then came four gods who said to him:


"It was to us, Rantideva, that you gave food, for we assumed the forms of a Brahmin, a Sudra, a dog and a poor outcaste. You were good to us all and we praise you for your loving thoughts."




A kind heart treats all men and even animals as members of one family, one humanity.

Orderliness

In the parlour of an old farmhouse there was an antique grandfather clock which for more than a hundred and fifty years had never ceased ticking faithfully. Every morning at daybreak when the farmer came down, the first thing he would do was to visit the clock to be sure that it was right. Now it happened one morning that as he went into the parlour as usual, the clock began to speak:

"For more than a century and a half," it said, "I have been working without a stop and keeping perfect time. Now I am tired; don't I deserve to take a rest and stop ticking?"


"Your complaint is unjustified, my good clock," the shrewd farmer replied, "for you are forgetting that between each tick you have a second's rest."


After a moment's thought, the clock began to work again as usual.


In orderly work fatigue and rest balance each other, and that regularity avoids much pain and effort.


At first it may take some pains to acquire order. Nothing can be learnt without an effort; nor is it easy to learn, but success comes little by little. 
After a certain time, we can learn to do things in an orderly way without the least difficulty. And more and more, we find disorder painful and disagreeable.
Order always in the end becomes a habit.
And above all, being orderly, regular, punctual, must not prevent one from being happy and smiling. It is not necessary to pull a long face when carrying out a task exactly. 

Self-Reliance

He was a prince of ancient times and his name was Gushtasp.

He was much annoyed that his father did not treat him as heir to the throne, so he left his native land and wandered to the West. Alone and hungry, he realised that from then on he would have to work for his living. So he went to the sovereign of the land and said to him:
"I am a skilled writer and I should be happy to be employed as a scribe."
He was told to wait for a few days, for no scribes were needed at the moment. But he was too hungry to wait, so he went to the camel-drivers to ask for work.
They did not need any new helper; however, seeing his dire need, they gave him something to eat.
A little further on, Gushtasp stopped at the door of a forge and offered his services to the smith.
"Here," said the man to him, "you can help me to hammer this piece of iron." And he placed a hammer in Gushtasp's hands.
The prince had tremendous strength. He lifted the heavy hammer, brought it down on the anvil and smashed it at the first stroke. The smith was furious and immediately turned him out.

And so Gushtasp started wandering once more in great distress.
Whichever way he turned, there was no way in which he could show his usefulness.

At last he met a farmer working in a cornfield, who took pity on him and gave him food and shelter.
One day there came the news that the daughter of the king of Rum was of an age to marry and that all young men of princely family were invited to the royal banquet. Gushtasp decided to go there and sat at table among all the others. Princess Kitaban saw him, loved him and gave him a bunch of roses as a token of her favour.

The king took a violent dislike for Gushtasp in his poverty. He dared not forbid his daughter to marry him, but as soon as they were married he drove them out of his palace. So they went to live in the heart of the forest and built their hut not far from a river.
Gushtasp was a great hunter. Each day he would cross the river by boat, catch an elk or a wild ass, give half to the boatman and take the rest home to his wife.
One day the boatman brought a young man named Mabrin to see Gushtasp.

"My Lord," said Mabrin, "I wish to marry the second daughter of the king, your wife's sister, but I cannot unless I kill the wolf who is ravaging the king's lands. And I do not know how to do it."
"I will do it for you," said Gushtasp the hunter.
He went out into the desert and when he found the monster, he shot it down with two arrows and then cut off its head with his hunting knife.

The king came to see the dead beast, and in his joy gave his second daughter to Mabrin.
Some time later, the boatman brought another young man named Ahrun to see Gushtasp. Ahrun wished to marry the third daughter of the king, but first he had to kill a dragon. Gushtasp promised that he would accomplish this new feat.
He took some knives and made them into a ball bristling with sharp points. Then he set out on his quest and found the dragon with fiery breath. He shot many arrows at the body of the monster, leaping from side to side to avoid its claws. Then he fastened the ball of knives to the end of a pike and thrust it down the dragon's throat. The dragon closed its jaws and fell. Then the prince dispahed it with his sword.

Thus Ahrun married the third daughter of the king.
You will not be surprised to hear that in the course of time such a valiant prince became the king of Persia in succession to his father. It was during the reign of Gushtasp that the holy prophet Zerdusht, or Zoroaster, taught the Persians faith in rmazd, Lord of light and sun and fire and of righteousness and justice.

None is more worthy of respect than one who, relying on himself, is able by his own effort not only to provide for all his needs, but to increase the well-being and the prosperity of those around him.

Introduction to CFD - Part V : Solutions

Solutions

Once the preprocessing is done, means once we have good mesh, we can import the mesh in specific solver are solve the desired governing equations. This step is called as solution step. The tools which take mesh as input and carryout the solution of selected governing equations are called as solvers. 

In typical solver we will be doing following steps:

a) Selecting the appropriate solvers

i) Pressure based or density based

b) Selecting the mathematical equations to be solved

i) Steady state or unsteady state equations

ii) Compressible of incompressible equations

iii) Laminar or turbulent flow equations

iv) Energy equation

v) Multiphase flow equations

vi) Radiation equations 

           And many more based on the physics you want to simulate

 c) Selecting the material properties

i) Fluid Material (Water, air etc...)

ii) Solid Material (Copper, Aluminum etc...)

d) Assigning appropriate boundary conditions

i) Inlet Boundary:

- Example 1 : Velocity Inlet with 10 m/s and normal to boundary

- Example 2: Total pressure at inlet = 101325 Pa (Gauge)

- Example 3: Mass flow rate at inlet = 12 Kg/s

ii) Outlet Boundary

- Example 1 : Pressure at outlet = 0 (Gauge)

- Example 2 : Mass flow at outlet = 10.2 Kg/s

- Example 3 : 50 % flow is going out of the outlet

iii) Wall Boundary

- Example 1 : Adiabatic and no slip boundary

- Example 2 : Constant temperature 400 K and no slip boundary

iv) Fluid domain conditions

- Example 1 : Working media is air and domain is rotating with 1000 rpm

- Example 2: Working media is water

v) Solid domain conditions

- Example 1 : Heat generation rate in solid = 20 W/m³

           Any many more depending on the problem that you are simulating

e) Selecting the Solutions controls

i) Selecting discritization schemes

- Example : 1^st order for pressure and 2^nd order for density

ii) Selecting under relaxation factors

iii) Selecting pressure correction methods

- SIMPLE/SIMPLEC/PISO

iv) Selecting the CFL number 

f) Providing the initial guess of the solution

g) Putting some monitors for getting idea about if my solution is converged or not

h) Carrying out the solution

You may not be in position to appreciate most of the above steps. But all the above steps will be explained in detail in chapters to come. You will come to know the meaning and importance of each and every step written above but the only conditions is you should keep on reading.

The overall idea of task carried out in solver is to solve the selected set of equations with specified boundary conditions for selected materials using selected numerical schemes

The type of numerical scheme and solution strategy will depend on which type of equations we will be solving, which type of boundary conditions we will be using and what type of geometry is involved in the problem.

Following chart will give an overall idea about inputs needed for any solver
