Hello.

00:02.060 --> 00:09.530
In this particular section, we will be going through an example with thermal simulation.

00:10.400 --> 00:18.160
I got a lot of requests from student asking to add a few examples so that it is easier for them to follow

00:18.160 --> 00:18.780
the course.

00:19.240 --> 00:20.370
So I thought, why not?

00:21.450 --> 00:30.960
Select an example from thermal physics and then solve that example so that people from different feel

00:30.960 --> 00:34.340
or different background can easily understand what is going on.

00:35.370 --> 00:38.190
So we'll be starting today in terms thermal simulation.

00:39.530 --> 00:42.030
Now, let's look how will set up the model.

00:42.650 --> 00:46.700
We will have a rectangular block, it could be a model.

00:46.910 --> 00:56.030
A conductor, basically a thermal conductor will heat from one side at 100 degrees Celsius and will

00:56.030 --> 01:04.940
put insulator on one side, and then we will set zero degrees Celsius on these two sides.

01:05.930 --> 01:14.150
Now, so the model looks something like we have a source here and we have a sink here with insulator

01:14.180 --> 01:15.170
on one side.

01:16.450 --> 01:21.340
And we will try to simulate it and see how the result actually looks.

01:22.760 --> 01:25.460
Of course, this is a connecter.

01:26.880 --> 01:31.140
Now, after we do the simulation, the results will look something like this.

01:32.900 --> 01:41.240
We have a region of high temperature, as you can see, it was 100 degrees Celsius, which is basically

01:41.450 --> 01:44.850
three hundred and seventy three Kelvin close to that.

01:45.290 --> 01:48.080
So this is the reason, a high temperature.

01:49.180 --> 01:58.840
This region is at zero degrees Celsius or two hundred and seventy three Kelvin and rest of the region

01:59.350 --> 02:01.910
is a gradient of the temperature.

02:02.440 --> 02:06.700
So this is consistent with the boundary conditions.

02:09.410 --> 02:15.860
Now, this is the thermal control, which will also learn how to plot isothermal control, as you can

02:15.860 --> 02:20.220
see that these are the isothermal control lines.

02:20.990 --> 02:29.210
Now as the top the right zero degrees Celsius, that's where the president isothermal control bends

02:29.360 --> 02:32.290
along the zero degrees Celsius line.

02:34.380 --> 02:39.390
So all these kind of plots we learn in this particular section.

02:41.160 --> 02:46.570
OK, without wasting our time, let's start the simulation.

02:46.800 --> 02:54.230
So in my next lecture, I will make the geometry add mesh and we will start solving.

02:54.570 --> 02:55.420
Thank you for watching.

02:55.590 --> 02:57.930
See you in my next lecture.
