WEBVTT 00:01.390 --> 00:02.270 Hello. 00:02.560 --> 00:09.400 In this video we discuss about the property groups now what is the use of property groups. 00:09.400 --> 00:16.720 Suppose you are working in a project that you have your own set of parameters. 00:16.720 --> 00:23.770 For example your thermal conductivity varies some kind of an exponential curve or something like that 00:24.280 --> 00:27.820 but that material is not present in use a library. 00:27.820 --> 00:29.410 So how will you do that. 00:29.590 --> 00:38.350 In those cases you have to use user defined property group what it means is the user will define the 00:38.350 --> 00:41.450 property of the meter deal in this group. 00:41.890 --> 00:47.680 So if you right click on a material you would have user defined property group or just select here. 00:47.740 --> 00:50.190 Then you have three different options. 00:50.210 --> 00:57.340 One you can add a function which is analytic you can use interpolation where you give the setup points 00:57.370 --> 00:59.020 and into interpolate. 00:59.050 --> 01:03.190 You can also add piece face function for example 0 to 1. 01:03.220 --> 01:07.000 It's linear 1 to 2 x parabolic and so on. 01:07.000 --> 01:15.520 You just have to click on one of the function and you write the expression and the argument. 01:15.520 --> 01:22.900 Similarly if you want to do some kind of interpolation it give the value of T and F of T and interpolation 01:22.900 --> 01:25.530 method and you will go to. 01:25.660 --> 01:28.000 Also you can use piece face function. 01:28.000 --> 01:36.520 For example you give the start and end point and the function you can add one more you can add multiple 01:36.520 --> 01:42.270 lines to have a piece Y's function. 01:42.370 --> 01:50.650 So I assume you with an example suppose from minus 1 to 1 I have X from 1 to 2. 01:50.650 --> 01:56.160 I have 3 x and so on. 01:56.200 --> 02:03.670 So if a plot you see from minus 1 to 1 I have X from 1 to 2 have 3 or something like that and then you 02:03.670 --> 02:12.400 have to use this function in terms of your property in the material that I am not going to cover in 02:12.400 --> 02:16.100 this course because that is totally a different thing. 02:16.150 --> 02:19.630 It will take probably many hours to go through that. 02:19.960 --> 02:26.740 So in this course I am not going to talk about how to use my tools in a simulation how to use user defined 02:26.740 --> 02:32.010 group and all these things that I do in 0 later of course. 02:32.110 --> 02:34.260 Anyway let's move on. 02:34.870 --> 02:37.390 So I hope this is clear for you. 02:37.420 --> 02:43.470 The property group is used mainly for user defined properties. 02:43.510 --> 02:52.300 Just remember that and there were people and also let me discuss about the user defined liability what 02:52.390 --> 02:55.160 each user defined liability as the term suggests. 02:55.180 --> 03:01.020 Suppose you create a material with a lot of properties or whatever is important to you. 03:01.060 --> 03:10.240 You rename the model liability and then you can always add to user defined liability. 03:10.870 --> 03:19.240 So when you click on add material at the bottom you have user defined library and inside that it you 03:19.240 --> 03:23.580 will have all the materials in the user defined library. 03:24.070 --> 03:26.090 Okay I hope this is clear to you. 03:27.160 --> 03:35.090 Let me recap what I have taught in the Maitreya series in the first section. 03:35.260 --> 03:41.470 You have the material you can add blank already made material which is a lower income so in the second 03:41.470 --> 03:48.220 video I discuss about the property group where you can use their own function to define your own property 03:48.700 --> 03:51.880 and then add that which will in your library. 03:51.880 --> 04:01.000 So this is the overall idea of the material window in comes metaphysics here I end the Section 4 matrix 04:01.300 --> 04:06.610 in my next section I'll talk about the physics incomes and metaphysics. 04:06.610 --> 04:08.760 That would be interesting too. 04:08.770 --> 04:09.530 Goodbye. 04:09.550 --> 04:13.110 Take care and I'll see you in my next video.
