WEBVTT 00:00.180 --> 00:02.250 Hi, guys, welcome back. 00:02.490 --> 00:09.060 So in this tutorial, we will learn how to analyze the results of our simulation. 00:09.360 --> 00:14.810 So our past lecture, we already computed our results. 00:15.120 --> 00:22.050 So let's go back to the result and then see how we can plot these different results. 00:22.380 --> 00:27.090 OK, so we have the results here just right. 00:27.090 --> 00:32.100 Click on the result and then click on one deployed group. 00:32.340 --> 00:36.570 Just remember that it actually depends on the type of physics you're using. 00:36.570 --> 00:43.380 Let's say you are using a 3D component which has data in X, Y, Z direction and stuff. 00:43.710 --> 00:49.810 So in that case, you might need to do 2D and one depending on your work. 00:49.830 --> 00:55.770 So basically the one day to day truly depends one on the type of work you are doing. 00:56.040 --> 01:00.990 Second, on the physics and the component dimension you are working. 01:01.020 --> 01:09.000 OK, so we have our deployed group now instead of one deployed group just right click. 01:10.690 --> 01:12.250 Click on Global. 01:15.650 --> 01:22.010 When you click on Global, you will have settings window like this, so global are basically used to 01:22.070 --> 01:31.310 plant this killer numbers, such as points up any data with respect to time, etc. So we can click on 01:31.310 --> 01:42.770 the expression, go to ad expression and then click on Electric Circuit then devices. 01:43.700 --> 01:51.800 Now know that when you add components in your electrical circuit, let's say if I go here and open up 01:51.800 --> 01:58.670 the electric circuit physics and then when I come back in the global. 02:00.040 --> 02:08.190 Plot and click on ADD explosion inside of electrical circuit devices, you will see that I have see 02:08.200 --> 02:15.670 one are one are two and one here also I have see one are one V1 and are two. 02:16.210 --> 02:24.010 So the components which are there in your physics will show up in their devices and the nodes. 02:24.010 --> 02:26.020 Similarly we have four nodes. 02:26.470 --> 02:29.800 The nodes are basically these nodes. 02:29.800 --> 02:34.180 Right, the source resistor, capacitor and so on the north you're using. 02:34.810 --> 02:39.130 So the nodes are actually the nodes which are used in the physics. 02:39.350 --> 02:41.350 I hope you understood the concept. 02:41.710 --> 02:46.470 So let's say I want to see the charging of a capacitor, the current. 02:47.230 --> 02:48.580 So just Double-Click. 02:49.540 --> 02:55.360 And now the expression will show something like this, which is the name of the component. 02:55.930 --> 03:06.640 Then see are for the physics that is the circuit csir dot c one underscore I so see one for the capacitor 03:07.030 --> 03:08.980 and underscore I for the current. 03:10.030 --> 03:18.430 OK, so to plot this, just click on plot and you will have your plot here. 03:20.000 --> 03:26.870 Now know that it looks a bit weird, it's just like a straight line, um, it looks like the simulation 03:26.870 --> 03:27.770 is not right. 03:28.550 --> 03:31.520 That's what I was telling in the previous lecture. 03:31.520 --> 03:34.450 That is, the study matters a lot in this kind of simulation. 03:34.940 --> 03:39.290 First of all, you must know the, um, time constant. 03:39.920 --> 03:46.460 Right, or the reference point or the type of circuit you are doing so far here. 03:46.640 --> 03:49.580 I can see that there should be some more points here. 03:49.580 --> 03:58.130 And, um, it's better to run the simulation on a smaller range that is between zero and zero point 03:58.130 --> 03:58.850 one second. 03:59.240 --> 04:00.440 So let's do that. 04:00.800 --> 04:07.280 I would go to study that this time dependent, uh, study and stop time seconds. 04:07.680 --> 04:14.600 What I will do is I will click on milliseconds so it will run from zero to zero point one until one 04:14.600 --> 04:15.290 millisecond. 04:15.440 --> 04:16.820 And let's see what happens. 04:17.480 --> 04:19.130 I click on compute. 04:21.770 --> 04:29.840 And now you see the results are just awesome, you can see that the charging of a capacitor is easily 04:29.840 --> 04:39.610 shown here in the graph and, um, let's increase the number of points because the curve is not smooth. 04:39.740 --> 04:41.270 It's like a straight line. 04:41.780 --> 04:45.200 So I will just add one more zero here. 04:47.530 --> 04:49.090 And I will compute once again. 04:51.160 --> 04:55.600 And now you can see a very beautiful curve of charging of a capacitor. 04:56.680 --> 05:05.440 Now, just to verify your results, what you can do is you can just open up any sheet, maybe an Excel 05:05.440 --> 05:08.550 sheet and try to just show the calculation. 05:08.560 --> 05:11.790 So I have an Excel sheet, which I've already done. 05:12.160 --> 05:19.330 And here you can see I have the one column, for instance, and one column for the capacitor. 05:20.050 --> 05:26.140 So if I go on the register, I have a thousand, which I have here. 05:26.140 --> 05:27.130 I have a thousand here. 05:27.820 --> 05:32.200 And similarly for capacitor, I have 109 offered. 05:33.070 --> 05:37.480 So if I converted to Ferid it is like a hundred by ten pound nine. 05:37.840 --> 05:40.090 OK, so when I calculate RC. 05:41.560 --> 05:51.240 I get zero point zero zero one, so if I see my plot, it is quite consistent. 05:51.250 --> 05:55.720 So you can see that it is zero point zero zero one, which is in the order of RC. 05:56.050 --> 06:01.340 That is what we learned in our theory lecture in the first lecture of our course. 06:01.360 --> 06:01.720 Right. 06:02.200 --> 06:10.600 So this is how easily you can calculate the charging, discharging and different kind of simulations 06:10.900 --> 06:12.640 in console using the circuit. 06:12.670 --> 06:18.370 Now, this is a very, very basic, I would say, the most basic circuit. 06:19.090 --> 06:24.900 You should always try if you are planning to use the electrical circuit in concert. 06:25.270 --> 06:32.440 So I will just link the actual sheet in the course resource page. 06:32.450 --> 06:38.730 So when you are following the course, you can just download the actual sheet, change the values under 06:38.740 --> 06:45.700 so you can put it five thousand and different, see different, uh, time constraint and you can play 06:45.700 --> 06:48.070 with it, verify with different examples. 06:48.970 --> 06:49.870 So that's it. 06:49.870 --> 06:56.770 In my next lecture I will just finish off this particular section with a little bit of in-depth analysis 06:56.770 --> 06:58.330 in the results. 06:58.720 --> 07:01.900 Thanks for watching and we will be back in our next lecture.
