Hello, this is a bonus lecture on this cause, so I got a request ask me to describe about the model
builder window.
So how am I getting all the options?
First of all, this is the route.
Uh.
Three, so if you consider this story and these are Salvatore's, this is the main street, which is
the fire, as you can see, the fire name is also present here.
Right.
So what can we do just right?
Click on the model, click on ADD component.
And if you want to do a 3-D simulation, you have to click through.
If you want to do a 2D simulation, you can click on duty and so on for one day and as symmetry cases.
So for now, I'll click on 3D.
OK, so when you click on 3D, you get a few options, that is definition and geometry, right.
And what is a global definition?
Global definition means whatever you define in commercial as a global definition, it will be accessed
throughout all the subjects in the simulation.
So, for example, if you have two or three different components, it can access the global definition
of values.
So that is by global definition means.
OK, so now we have a component in the geometry.
Let's just draw a block.
OK, so we have a block and we have material.
So after we create a geometry, we have to admit that is, uh, if this block is made up of copper,
aluminum or anything as such, next comes the mesh.
So after we add material, we have to mesh the model right now.
What you do after this, but we can do is we can go to physics and then click on Add Physics.
When you click on Add Physics, we get some window like this insight and physics.
You have these options.
For now, I just take heat transfer in solid.
So just open up the heat transfer.
Right, click click on add to component one.
As you can see, this is named this component one.
So I'll click on component one.
Wait a few seconds and you will see that the physics heat transfer in solid will be added to the model,
right?
Now you need to add a material, right, click, click on that material and it will ask different properties.
So I'll just add one one one just for simplicity, depending on your simulation.
We will have different values of thermal connectivity, density and heat capacity because these properties
are needed to simulate a heat transfer physics.
So, for example, if you use a different physics, for example, the AC DC module, chemical species
transport and.
Different module, for example, acoustic modules, you will need different properties, so for heat
transfer in solid module, you need these three properties for this information.
So that's why the software is asking these three properties.
OK, that's great.
So what more things we do need to run a simple simulation, we need a study after we make the model,
we need to simulate the two, how to simulate.
We have to add a study so we can study.
If I want to have a stationary study, I'll click on stationary study right click click on ADD to study
when you click on air study so the tree will look something like this.
At first it has to mean absolutely.
After that it has the global definition and then comes the component in set component.
We have the geometry material, the physics and the mesh.
Also, we have the definition that is not important for now.
There is for advanced reading and all.
For example, you can change the view styles and all.
So that is not relevant for discourse.
And next comes the study inside study.
We have this disparity study here.
If you click on compute, the software will try to calculate the simulation values.
After we have done with the simulation in the results section, we have the result.
So when the simulation is done, the data set will have all the data for the simulation and then we
have the plots inside the address.
And so all the post-processing work is done in the simulation is done in study.
The physics and the geometry is defined in component.
So the geometry will make the geometry of the model which you are working the material.
We add the material.
So if it is made out of copper, glass, air or whatever.
The physics actually defines the boundary condition and the equation, which is followed by the moral
dimension, will define the model into smaller sections so that it can easily solve the differential
equations for the given simulation.
So that's it.
I guess that now you are much clearer about the model builder than, uh, that's it.
I hope that you have learned something from this lecture.
Thank you for watching.
See you around.
