WEBVTT 00:00.990 --> 00:14.340 Hello, this is a bonus lecture on this cause, so I got a request ask me to describe about the model 00:14.610 --> 00:15.570 builder window. 00:15.750 --> 00:18.020 So how am I getting all the options? 00:18.390 --> 00:22.380 First of all, this is the route. 00:23.460 --> 00:24.090 Uh. 00:25.280 --> 00:30.950 Three, so if you consider this story and these are Salvatore's, this is the main street, which is 00:30.950 --> 00:35.330 the fire, as you can see, the fire name is also present here. 00:35.670 --> 00:36.080 Right. 00:36.890 --> 00:41.800 So what can we do just right? 00:41.900 --> 00:46.430 Click on the model, click on ADD component. 00:46.820 --> 00:49.880 And if you want to do a 3-D simulation, you have to click through. 00:50.510 --> 00:57.500 If you want to do a 2D simulation, you can click on duty and so on for one day and as symmetry cases. 00:57.890 --> 00:59.780 So for now, I'll click on 3D. 01:02.290 --> 01:11.680 OK, so when you click on 3D, you get a few options, that is definition and geometry, right. 01:12.310 --> 01:14.920 And what is a global definition? 01:15.320 --> 01:24.220 Global definition means whatever you define in commercial as a global definition, it will be accessed 01:24.610 --> 01:28.750 throughout all the subjects in the simulation. 01:28.930 --> 01:35.380 So, for example, if you have two or three different components, it can access the global definition 01:35.800 --> 01:36.440 of values. 01:37.180 --> 01:39.310 So that is by global definition means. 01:39.790 --> 01:44.940 OK, so now we have a component in the geometry. 01:45.400 --> 01:47.870 Let's just draw a block. 01:48.220 --> 01:55.990 OK, so we have a block and we have material. 01:56.350 --> 02:03.400 So after we create a geometry, we have to admit that is, uh, if this block is made up of copper, 02:03.430 --> 02:08.890 aluminum or anything as such, next comes the mesh. 02:09.610 --> 02:17.570 So after we add material, we have to mesh the model right now. 02:17.590 --> 02:26.200 What you do after this, but we can do is we can go to physics and then click on Add Physics. 02:27.250 --> 02:33.040 When you click on Add Physics, we get some window like this insight and physics. 02:33.490 --> 02:35.170 You have these options. 02:35.980 --> 02:39.840 For now, I just take heat transfer in solid. 02:40.180 --> 02:42.490 So just open up the heat transfer. 02:42.850 --> 02:46.210 Right, click click on add to component one. 02:46.660 --> 02:49.750 As you can see, this is named this component one. 02:50.620 --> 02:52.600 So I'll click on component one. 02:54.470 --> 03:03.790 Wait a few seconds and you will see that the physics heat transfer in solid will be added to the model, 03:04.400 --> 03:04.850 right? 03:08.700 --> 03:19.100 Now you need to add a material, right, click, click on that material and it will ask different properties. 03:19.320 --> 03:25.080 So I'll just add one one one just for simplicity, depending on your simulation. 03:25.120 --> 03:31.050 We will have different values of thermal connectivity, density and heat capacity because these properties 03:31.050 --> 03:34.810 are needed to simulate a heat transfer physics. 03:35.400 --> 03:41.400 So, for example, if you use a different physics, for example, the AC DC module, chemical species 03:41.400 --> 03:43.080 transport and. 03:44.140 --> 03:50.230 Different module, for example, acoustic modules, you will need different properties, so for heat 03:50.230 --> 03:56.180 transfer in solid module, you need these three properties for this information. 03:56.560 --> 03:59.410 So that's why the software is asking these three properties. 04:01.060 --> 04:02.170 OK, that's great. 04:02.800 --> 04:10.720 So what more things we do need to run a simple simulation, we need a study after we make the model, 04:11.200 --> 04:14.860 we need to simulate the two, how to simulate. 04:14.890 --> 04:18.100 We have to add a study so we can study. 04:19.450 --> 04:27.370 If I want to have a stationary study, I'll click on stationary study right click click on ADD to study 04:28.960 --> 04:32.830 when you click on air study so the tree will look something like this. 04:33.230 --> 04:36.600 At first it has to mean absolutely. 04:36.940 --> 04:42.570 After that it has the global definition and then comes the component in set component. 04:42.580 --> 04:46.390 We have the geometry material, the physics and the mesh. 04:46.910 --> 04:50.880 Also, we have the definition that is not important for now. 04:51.190 --> 04:54.660 There is for advanced reading and all. 04:54.700 --> 04:57.630 For example, you can change the view styles and all. 04:58.000 --> 05:00.240 So that is not relevant for discourse. 05:01.260 --> 05:04.950 And next comes the study inside study. 05:05.250 --> 05:08.010 We have this disparity study here. 05:09.860 --> 05:16.050 If you click on compute, the software will try to calculate the simulation values. 05:16.920 --> 05:23.430 After we have done with the simulation in the results section, we have the result. 05:23.970 --> 05:32.490 So when the simulation is done, the data set will have all the data for the simulation and then we 05:32.490 --> 05:34.310 have the plots inside the address. 05:34.340 --> 05:41.340 And so all the post-processing work is done in the simulation is done in study. 05:41.850 --> 05:46.150 The physics and the geometry is defined in component. 05:46.800 --> 05:53.610 So the geometry will make the geometry of the model which you are working the material. 05:53.610 --> 05:54.790 We add the material. 05:54.990 --> 05:59.190 So if it is made out of copper, glass, air or whatever. 06:00.750 --> 06:08.760 The physics actually defines the boundary condition and the equation, which is followed by the moral 06:09.690 --> 06:15.780 dimension, will define the model into smaller sections so that it can easily solve the differential 06:15.780 --> 06:18.330 equations for the given simulation. 06:18.840 --> 06:19.580 So that's it. 06:19.830 --> 06:28.710 I guess that now you are much clearer about the model builder than, uh, that's it. 06:29.100 --> 06:32.200 I hope that you have learned something from this lecture. 06:33.180 --> 06:34.210 Thank you for watching. 06:34.380 --> 06:35.910 See you around.
