WEBVTT 00:01.170 --> 00:01.820 Hello. 00:01.860 --> 00:02.680 Welcome. 00:02.730 --> 00:13.020 In this video we'll talk about the section study in study what we have is we can add a study we can 00:13.020 --> 00:15.300 define what type of study we want. 00:15.480 --> 00:18.050 And also we can work on this solution. 00:18.120 --> 00:22.680 So basically after you create your simulation model and physics add mesh. 00:22.830 --> 00:26.270 The next step is to study the simulation. 00:26.490 --> 00:28.020 So let's go one by one. 00:28.410 --> 00:33.630 When you click on compute it will start computing your simulation. 00:33.660 --> 00:38.840 So this is basically a trigger button for your simulation. 00:38.850 --> 00:45.290 Now this option is used to select the study you want to run. 00:45.810 --> 00:49.530 If you have multiple study it will show up in our study. 00:49.530 --> 00:58.220 You can add a new study object solution will update the solution get initial value as the title says 00:58.230 --> 01:00.810 it will get the initial values. 01:01.290 --> 01:02.430 So default solver. 01:02.430 --> 01:05.900 This is not that useful study steps. 01:05.940 --> 01:08.150 Now this is interesting. 01:08.160 --> 01:11.460 Suppose you are doing a kind of simulation which is time dependent. 01:11.550 --> 01:14.600 Then you have to select time depending on study. 01:14.610 --> 01:17.700 Suppose your simulation is dependent on frequency domain. 01:17.700 --> 01:20.370 Then the FSS frequency domain. 01:20.370 --> 01:24.040 Similarly a web then domain and other things. 01:24.170 --> 01:31.380 So depending on the type of study you are doing you have to select the study in this parametric sweep. 01:31.380 --> 01:38.190 Now when you click on parametric sweep it will come up an option like this is basically when you define 01:38.220 --> 01:45.180 a barometer in your global definition and you click on plus those by me just will show up here and you 01:45.180 --> 01:47.190 can run the perimeter. 01:47.490 --> 01:54.810 Suppose for example I want to change the height of the skew from one centimeter to two centimetres Three 01:54.810 --> 01:56.600 centimeter and four centimeter. 01:56.700 --> 02:08.130 I can just write one space to space three space four and then if I click on compute it will take the 02:08.250 --> 02:14.220 height as one centimeter run this simulation take the second height as two centimeter run the simulation 02:14.220 --> 02:15.930 and so on. 02:15.930 --> 02:20.760 So it will have four different studies for four different parameters. 02:20.760 --> 02:23.620 This is basically a parametric sweep. 02:24.810 --> 02:32.190 Similarly a functional sweep if you have different functions and you want to run all at once. 02:32.190 --> 02:38.370 Also if you have Metro you'll see images see if you have to create a material switch. 02:38.370 --> 02:45.900 So it's basically supposing you have 10 different kinds of metal and you want to run a simulation for 02:45.900 --> 02:50.640 copper iron nickel corporate and all those matters. 02:50.700 --> 02:58.620 One by one in a automatic fashion in that case you can use materials where all the simulation will run 02:58.680 --> 03:01.750 automatically by changing different materials. 03:01.930 --> 03:08.430 You have a combined solution feature which I have not honestly used steady reference. 03:08.670 --> 03:14.490 So uh you can refer one study to another and proceed. 03:14.850 --> 03:24.900 Optimization is used to optimize your study by meta estimation is used to estimate a tiny parameter 03:25.200 --> 03:25.620 by the way. 03:25.620 --> 03:28.530 This is a very interesting tool. 03:28.650 --> 03:35.750 So in optimization of a study you can optimize your simulation. 03:35.760 --> 03:42.480 For example you want to minimize or maximize a kind of simulation you can do that using optimization. 03:42.480 --> 03:48.150 I will not go into every detail of this because this is quite complicated if I try to explain all this. 03:48.150 --> 03:52.140 It will take like five hours for each of this option to explain. 03:52.140 --> 03:54.810 So basically I am just giving an introduction. 03:54.840 --> 03:56.230 What are these. 03:56.480 --> 04:02.690 I said Next we have sensitivity sensitivity. 04:02.810 --> 04:08.340 Uh I have never used it but most probably it is some kind of a measure. 04:08.620 --> 04:12.200 All these sensitive analyses mother's reaction. 04:12.230 --> 04:13.680 Also I have not used. 04:13.680 --> 04:19.820 I am sorry that I can't help you with these two options as I have never used in Baton cluster. 04:19.850 --> 04:25.940 Suppose you are running a very big simulation in those cases you run your simulation in a question. 04:26.390 --> 04:31.850 So these two options are for that if you are running a simulation in your own personal computer then 04:31.910 --> 04:33.750 I don't think this is useful to you. 04:35.070 --> 04:39.700 We can create a solution copy in this option in statistics. 04:39.710 --> 04:47.100 If you click on statistics it will show a few details about a simulation for example the temperature 04:47.140 --> 04:49.850 module number of degrees of freedom. 04:49.850 --> 04:53.060 The total number because that freedom and so on. 04:53.060 --> 04:57.620 If you click on your solution it will clear your current selected solution. 04:57.620 --> 04:59.490 If we clear all solution. 04:59.630 --> 05:05.060 So if you have for example your parametric solution your functional sleep solution you have different 05:05.060 --> 05:07.340 study all the solution will be clear. 05:08.300 --> 05:16.280 Now whenever you are running a big program the file size could vary for one GV B2C be 3G vs n huge size 05:16.310 --> 05:23.510 because it s having the mass data it s having the solution data and all those things. 05:24.230 --> 05:32.510 So when you are saving a file you can clear your solution then the file say is will get reduced like 05:32.660 --> 05:39.140 five NBA or so and then you can send the file to your group member and then he or she can read on the 05:39.140 --> 05:40.400 program and get the data set. 05:40.820 --> 05:43.580 So that is one use of clear solution. 05:44.550 --> 05:45.040 Okay. 05:45.170 --> 05:46.520 Thanks for watching. 05:46.520 --> 05:49.580 In my next lecture discuss about results.
