 And we are starting the next session. It's going to be a hands on session using spoken tutorials once again. And the topic is creating 2D channel geometry and mesh in open form. So our team members are here from CAB open form team of FOSSE. Mr. Abhishek Naregmi will take it forward. Over to you Abhishek. So let's start our new session, hands on session using spoken tutorial. And this session is titled creating 2D channel geometry and mesh in open form. Here you are not going to do any simulation. You are just going to create a channel geometry and then mesh it. I'm going to provide link of spoken tutorial in the chat box. You can just go there. And in this tutorial you have to download a code file which you can do from the same website just at the right side. There's a icon, code files. You just have to click on it. Then it will download code file and you can extract that file and then use the file that is required for this spoken tutorial. You just have to follow this spoken tutorial and at the very end, you need to follow the same procedure that was used last time to see or view the results using paraform or paraview. OK, you guys can start doing this tutorial. Just like last time, I'm going to give you guys 15 minutes for this tutorial. And this tutorial is relatively very easy to follow. No, I'm not sharing any screen right now. You just have to follow this tutorial link. So it's already 18 minutes. How many of you were able to complete this? Can you raise your hand? OK, we have a couple of raised hands. So I hope everyone is able to do this spoken tutorial by themselves. So I'm going to briefly show you guys how to do this. I'm going to be very brief because we have to save some time for other tutorials as well. So I'm going to present my screen. I hope my screen is visible. Yes, sir. OK, so I'm in my run directory. If I do ls, I don't have any file called channel 395. So I'm going to copy the channel 395 using the same command that you guys have used. So here, after doing cp-r, the first directory is the file that I'm copying. I'm trying to copy channel 395. And this dot represents that I'm going to paste it here in my current directory, which is run. Someone was asking me the question, what is this dot represents? It represents that. It means the current directory. So now when I press Enter, it copies this channel 395 case. So now you can see I have channel 395 in my run directory. So I'm going to go to channel 395. And I'm going to remove my zero folder. Now I'm left with only this. So I'm going to open notepad.exe system and block mistake. So I'm going to open my block mistake using notepad.exe. So I'm going to remove all these things. Then I'm going to go to my, I'm going to go here, from where I've downloaded my files. I'm going to copy this thing. And then I'm going to paste it over here. And then I'm going to save it. So in this spoken tutorial, it was explained what is this vertices, what is this block, and how these boundaries are defined. I'm not going to do that again. You can, if you have some doubt, you can go back to the tutorial and watch it again. And if you still have some doubt, then you can write to us. We'll be happy to remove your doubt. Now that I've done that, I've saved it. I'm going to do blockness. And my blockness is done. Now I'm going to do dots result.fo. This will create a result.fo file in my directory. So I'm going to open this directory in file explorer using explorer.exe space dot. And I'm going to open this step. This time I don't have to go through that open with thing because now my system recognizes a paragraph. So I'm just going to open it and I'll click on apply. And here on surface, I'll click here and click on surface with edges. Now you can see how the message, the number of division that was done in x-direction. If you count here, it will be equal to the number that you had given in that line hex and your block mistake. And the same on the y. On z-direction, you had provided one. That's why we only have, we have no division on the z-direction. So this is how you mess 2D geometry, channel geometry using open form. Oh, sir, could you open the directory where channel 395 stored one somewhere exploded? Okay, you mean this run channel 395 this thing? No, no, the first one which you copy pasted the original place. Okay, you want me to go to the original place? Yeah, yeah. Okay, to do that. So I have a shortcut. If I do to it will get me to the tutorial directory. This shortcut will open, walk in all of you guys also tutorial. And if I do LS, I have different tutorials from open form directory. I'm going to go to this incompressible. So CD incompressible. And if I inside the incompressible, I have different tutorials for different solvers. So I'm going to go to pimple form. And here I have alias, alias and lamina. Since we were using alias, I'm going to go to CD alias. And here you can find channel 395. This doesn't exist, sir, in my... You might be using some other version of open form. Yeah. That could be the reason it doesn't exist. It might exist, but it might exist in some other location. You just have to figure it out. You have to source for it. Okay. Thank you. So I'm going to stop this tutorial because we are already past 25 minutes. I hope everyone is able to follow the tutorials. If you have some questions, you can ask now. Can you cross check the dimension in the Paraville? So yeah, you can cross check the dimension in Paraville, but there's a way to do it. So if you would like to find the dimension, you can click on this scale thing. And then you can here provide the, in point one, I'm giving this location and in X, I'm going to give one and then click on apply. So this will give me the length. So depending on what you might have put in the optimistic, we can put the original thing. Let's see. So can anyone tell me what was the second point? I can figure it out by going here also. So my second point was four meter long. So it means if I do your four, and then press enter and then press apply. So this is showing me a distance that is four meter long. So as you can see, it exactly matches with the geometry. So it means it is indeed four meter long. So this is how you can verify it. So can't we see the coordinates directly? Is there any command for that? Yeah, suppose I want to see the coordinates, all coordinates at the same time. Is there any way to do it? Yeah, there is a way to do it, but I don't think it works in double SL. I think you can go to access grid and check that. Yeah, you can do that as well, but this is a much easier way. What you can do is type paraform dash block. Yeah, that should be applied. So here you can see the numbering of the block that was made, how it was done. However, to do this, you need to enable your graphic, in your double SL, if you have Windows 11, it works by default, but if you have Windows 10, then it won't work. Okay, so now I would like to, we are running out of time and we also need to do one more, another session. So I'll just see if anyone has any questions. Sonia, explorer.exe command is not working. I think you forgot to give a dot at the end. So explorer.exe is space dot and that dot represents you want to open the current directory, the one you are switching. So this is not a simulation, just one thing, this was just messing. We just mazed a 2D channel geometry. Now, if you were not able to do this, no problem, we are again going to do a similar book on tutorial. And this time you were- Hello, sir. Yes, Ringatesh? Yes, sir. Actually, I didn't get anything, sir. Morning itself also, I didn't get anything, sir. I got the error, when I enter the first command is so like no source file. Sorry? Showing like that, sir. No? No source file, source file. I can put it in the chat box also, sir. Okay, you can put in the chat box. We have to start another tutorial as well. You put your queries in the chat box, whatever either you get, we'll try to solve it. Sir, I'm showing like this error, sir. Okay, so before that, I'm going to start the next tutorial.
