This is a typical window for conservative physics.
Whenever you launch the software into this kind of interface.
Okay you can select model wizard or you can select blank model now in blank model.
There are three options you can do 3D simulation for example a 2D cylinder you can do to the simulation
where is 3D cylinder can be represented by a circle.
If the system is such that it doesn't matter if you're doing 3D or truly simulation you can do one day
simulation so you can reduce the circle into a ring.
Now all the three courses are not same.
For example if you're working on system for example particle flow dynamics and so on 3D simulation might
be very time intensive.
It can take up to days to simulate then what people do is reduce the problem into a 2D circle.
I study the physics which might take maybe 4 to 5 hours even if it is fine to do a one day simulation
such as a ring.
It might take maybe a few minutes
to do the problem.
I will explain you what are truly truly and one day simulation.
For example I have a line I defined a line for example I'm explaining one day simulation.
Okay.
This is one day I have a line and I want to solve this writing equation so I have infinite potential
well so these are infinitely high.
And this is a well v equal to zero.
So how do you want the simulation.
You mark a line put two darts and you tell the software.
Does this region have infinitely high potential and this region has infinitely high potential.
And this is v equal to zero okay So note that we could have solved the problem by making a 3D model
and defining a d region as infinitely high potential and this as V equal to zero.
And this is also equal to infinite.
But this is not useful to us.
We can do the simulation in 1 D just by defining that we have infinite potential like two sides and
zero potential at the center.
So you can see how we can reduce a truly problem into 2D problem and what are we gaining from this.
First of all if we do a 3D simulation you have to take up the making this a militant time the results
and so on.
For example the Edge edge effects and other phenomenons but in one day you don't have to care about
all those.
All you have is a line you defined the properties up the line at various points and do the simulation.
Okay okay.
So let's start in file.
We have these options which is similar to every software in home.
We have a model builder window okay.
And go through this window one by one.
So this is a model builder window here.
We'll have all the options while doing the simulation for example the mesh the 3D model the physics
the deserts analyses and everything.
This is the setting window where we put all kind of boundary conditions and so on.
This is the graphic window where we will see our model for example.
In this example I will solve a cylinder to calculate the resistance of a cylinder.
This will be present in the graphics window.
Here you have components.
These are the parameters.
These are the variables we can add material.
For example copper iron etc. This is used to add physics.
This used to add study and so on.
Okay now these are.
This is the material library you can add as many materials as you want.
This is the study.
The research section for example you know you can work with to reply to the plot one day blah blah blah.
And so on.
You can have a guideline plot everything you can do basically.
Okay now I'll go to file new blank model.
So this is the interface of a blank model.
Now I do a truly simulation so I right click Add to.
See we have these options 0 0 1 the one the symmetric to the duly symmetric 3D and so on.
So I select to know that when I select 3D I have an option for geometry which is the meter centimeter
and so on I'll do centimeter.
Now I'll go to geometry add a cylinder and what is the radius of the cylinder one and let the height
be done.
I think this is fine and the pacing is fine.
Now when I click on bills or object it will be less in order for me.
You can see I have a cylinder of radius 1 centimeter and a height of 10 centimeter.
So this is 2 centimeter diameter and this is 10 centimeter.
Okay.
Okay fine.
So I have the cylinder ready.
Now what is the cylinder made of.
And I have go to material I have to add a material.
Let's say I want um copper
so I search for some materials maybe in July.
B let's click on copper and add to comprehend one Okay this is done.
So I have copper and I have selected one.
This is so very clear.
You see I have a cylinder but copper is not selected.
Now I'll click on copper and I click on the object you see here one will show up.
This means one is the cylinder.
For example if we have different objects you can select different materials for different objects.
And these are the uh these are the properties of the copper.
If we want you can change our laws.
So this is totally cool.
Now I have created a model.
I have said the materials.
Now it's time to create the mesh.
But before creating the mesh uh I think I should go with the introduction once again.
So I have a new you know what I did I created a component truly competent and in geometry I created
a cylinder of radius 1 centimeter and height 10 centimeter and then I chose the material to copper.
You could have chosen different material find in my next video I will show you how to mesh the object
so this is uh for the video in this video I showed you how to create a geometry how to draw geometry
basically and how to add material to geometry.
Also I'll show you a simple example.
For example you want to create a complex object let's say I go on to create a spear of one centimeter
at the center.
So you do build all object.
You have a spear but you can't see because there is no the spear is one centimeter.
So let's Jaws one point five centimeter radius.
You see I have a spear and a cylinder.
Now if you go to boolean partition and click on different object to add you add an object as the cylinder.
And what is the object you are on the substrate.
I click on the spear.
What happens when I click on B on.
I get a cylinder with one side which is bulging inward.
What happens is that I have a cylinder okay.
No I have a spear
what I did.
I added this cylinder and substructure the spear.
So what happens when I do that I get a cylinder with one side bulging inward.
So in my next video I will show how to mesh and what is meshing and why that is one of the most important
part in any kind of simulation.
Okay.
Thank you.
