WEBVTT 00:00.690 --> 00:00.960 Hi. 00:00.990 --> 00:02.000 Hello. 00:02.010 --> 00:04.900 In my last video I explained how to create the mesh. 00:04.900 --> 00:08.900 The How do I do physics and how do I make videos have the larger imagery. 00:09.270 --> 00:11.980 Almost 70 percent of this stuff is. 00:12.270 --> 00:16.440 Now the most important part How to Study the given system. 00:16.440 --> 00:23.990 We go to study and there are different ways we can study a given system since our system is not independent. 00:24.000 --> 00:28.420 It is just our DC voltage and the ground so we will go to stationary. 00:29.170 --> 00:34.630 We will level pick and study section we will come up fine now. 00:36.330 --> 00:44.010 We don't have to choose any settings mesh select to mesh one and will click on. 00:44.730 --> 00:50.250 Let me close this will click on compute when I click on compute the simulation software will calculate 00:50.250 --> 00:52.660 the physics and give us the dessert. 00:52.760 --> 00:59.140 Let me explain when I click on compute it will take some time. 00:59.330 --> 01:04.910 It was short some details here and the simulation is done. 01:05.000 --> 01:09.080 Let me explain one by one what is happening now. 01:09.440 --> 01:16.750 When a simulation is done in the desired section all the results will be shown. 01:16.760 --> 01:28.280 Now if I go to desert and click on 30 plot group and again I clicked on a volume the software will calculate 01:28.280 --> 01:32.640 the volume of the geometry. 01:32.660 --> 01:36.730 This debate matters in that volume the geometry. 01:37.070 --> 01:45.720 When I click on plot it will show me the potential profile of the cylinder. 01:45.750 --> 01:46.880 The expression is V. 01:46.910 --> 01:56.460 That is void and you can see that one void is at this end and 0 is at this end. 01:56.540 --> 02:01.730 So it is basically like a battery one for battery. 02:02.240 --> 02:09.220 This is a resistor where the connectivity is hundred seamen by meter. 02:09.830 --> 02:10.620 Nice. 02:10.670 --> 02:13.640 I think this rhetoric is quite interesting to you. 02:14.150 --> 02:20.690 So what more can we do with this. 02:20.720 --> 02:22.850 This is just the beginning. 02:22.940 --> 02:25.290 As we all said the tip of an iceberg. 02:25.310 --> 02:27.040 What things we can be doing comes up. 02:27.360 --> 02:29.150 So this is the truly plot. 02:29.420 --> 02:35.620 Now you want to show us what you want to show. 02:35.630 --> 02:39.710 You want to show the electric field or something like that. 02:39.740 --> 02:41.990 Okay let's select results. 02:43.310 --> 02:52.330 Do replied group and I too replied I chose surface No. 02:52.700 --> 03:03.560 If you click on defined cut plan so the software will blocked the potential across this card section 03:04.290 --> 03:10.730 and I click on blocked it will block the electric potential across the cross section so you can select 03:10.730 --> 03:14.600 some different point. 03:14.690 --> 03:16.960 Now if you click here 03:21.840 --> 03:22.650 it is inclined. 03:22.690 --> 03:28.340 Okay now you see that a very large region is selected. 03:28.390 --> 03:34.260 If I click on blog you can see the potential profile is being shown which is just this cross section. 03:34.420 --> 03:35.060 Okay. 03:35.290 --> 03:38.920 I think this is one of the most interesting thing you can do with this now. 03:41.930 --> 03:45.510 Okay so you might ask okay why you were just observing the potential. 03:45.710 --> 03:46.950 I want to see something else. 03:46.980 --> 03:49.480 Oh that's totally fine brother. 03:49.790 --> 03:51.330 Let's go to follow him. 03:51.470 --> 03:54.230 And in this expression you can click here. 03:54.230 --> 03:57.170 You can go to electric current and go electric. 03:57.170 --> 04:00.320 Let me plug the electric field x component. 04:00.380 --> 04:06.080 If you click on the blog you see the x convertibility fuel is being locked which is nicely because the 04:07.130 --> 04:09.000 potential is through Z. 04:09.290 --> 04:12.110 So X axis will make no sense. 04:12.110 --> 04:16.480 You see X is in this Y is in this and Z in this. 04:16.710 --> 04:25.570 So when I click on See that is Z which is the z component of electric fuel and click plot. 04:25.670 --> 04:40.630 You see it is an easy way because we know that little food is a dirty motive of the potential. 04:40.870 --> 04:46.930 Now the potential is linear. 04:47.710 --> 04:48.190 You saw 04:51.400 --> 04:53.260 the potential is linear. 04:53.260 --> 04:55.250 I'll show you once again. 04:55.390 --> 05:03.230 So when you click on potential the gradient is linear so the dignity of any alien thing is constant. 05:03.230 --> 05:08.140 That's why the electric field was coming out cleaner. 05:08.170 --> 05:10.880 I will show you again with a proof. 05:10.910 --> 05:17.860 Okay so I will have one deplored group and uh length line graph. 05:17.980 --> 05:19.270 Okay. 05:19.410 --> 05:22.860 And we'll have expression v defined cut line. 05:22.900 --> 05:31.100 Now we have a red line you can see now the sulfur filled plant with respect to the red line which is 05:31.280 --> 05:33.140 passing through the center of the cylinder. 05:33.140 --> 05:46.780 When I click on plot you see that the potential is 1 in 1 in and 0 at the other and the length of the 05:46.780 --> 05:55.300 cylinder was 10 centimeter so this is the one day plot of the potential. 05:55.360 --> 06:06.870 Now if I click on you see dart e see you see Detective feet is 90 and it is because the B potential 06:07.620 --> 06:09.050 is linear. 06:09.120 --> 06:20.420 So in this I showed you how to block a truly blocked off uh system b to be blocked off a cross section 06:20.780 --> 06:26.150 as well as the one D blocked one block so uh. 06:27.480 --> 06:30.230 So this is uh the recap. 06:30.230 --> 06:32.510 Okay uh a little one by one. 06:32.520 --> 06:35.450 What were things we did it could be too much for you. 06:35.480 --> 06:37.010 So let me tell. 06:37.010 --> 06:37.580 One by one. 06:37.580 --> 06:39.290 Let me open everything up. 06:39.810 --> 06:47.850 So if you have the root folder we created a the complaint here because we are working on 3D okay. 06:48.050 --> 06:53.770 So we have a truly component here. 06:54.280 --> 07:01.680 Then we created a geometry a cylinder we could we created the material on what material working we added 07:01.690 --> 07:08.620 the physics here we added the measures and then we added a study what we are studying then we did the 07:08.620 --> 07:11.260 analysis with our results. 07:13.240 --> 07:22.270 So this is the last lecture of my basic comes of course in my next lecture which will be the final lecture 07:22.270 --> 07:23.450 I'll explain. 07:23.510 --> 07:29.800 Few detailed calculation the things you can do using comes all multi physics. 07:29.800 --> 07:30.150 Thank you.
