 We will start with the hands-on session on creating 3D pipe geometry and the mesh in open form. So over to Abhishek. So now the next hands-on session using smoke-on-tutuja is going to be on creating 3D pipe geometry and then mesh it. So till now the geometry that you have meshed is a square rectangle geometry. Now you are going to mesh a circular or a pipe geometry, like a circular pre-chamber system. I am going to provide the link for that now. I hope all of you have received the link and you just have to follow this tutorial, the procedure for following this tutorial is the same as before and if you have any problem just type your error, whatever error you receive in the check and we will solve it. Sir, in my cavity folder there is no cavity pipe folder is there. So I think you missed the space, after 2 cavities there is a space, is that so? No sir, I have written cavity only. Can you just paste the command that you used to copy in the checkbox? So Tanmay I think you typed the command mistake, instead of icofoam there is incofoam, that is the mistake. That was for Tanmay by the way. If you are having trouble copying it, Binayak had just pasted the command to copy so that you guys don't have to make any trouble figuring out where the mistake is. But sir, in my incofoam solver there is cavity but in cavity folder there is no cavity pipe folder, only 3 type of folder is there. As I was saying, there is no cavity pipe but there is a cavity and at the very end there is a space between cavity and pipe. I think you missed the space. Okay sir, I am trying. Just copy the command that Binayak has given. Hi Eshan, I am Joseph. Actually, for openform I am using openform 9 actually. So in my incofoam cavity pipe is not there. Okay, you are using openform 9, I see. Inside cavity there should be another cavity file, right? Inside cavity there is cavity and then there are other cavities. Okay, you are just copying that cavity file and you are renaming it as pipe. Pipe that's a lot. Yeah, so there is a space between cavity and pipe. Yeah, I am not doing that. Okay, fine. Okay. People who have completed the tutorial can raise their hand. Hello sir. Yes. Sir, actually I am getting same issue, there is no pipe in cavity. Okay. Never mind. People who have completed, very good. And even if you have not completed, I am going to show you how to do it now. So you can just follow me. I am going to be very brief. So many people I think have trouble copying the file, right? So let's see. I am using openform 9 and this box in openform 789. So when I do cp-r and I am going to form tutorial, see I am not going to type whole tutorial. I am only going to type tu. Then I am going to press tab, my tab. So what it does, it automatically completes the sentence, the command. So when I press tab, see it automatically completed it. So I am going to press slash, then inc, then again I am going to press tab. It will automatically complete it. If you do this, you will know that you are not making any spelling mistake. If you were to make any spelling mistake, then when you press the tab, it won't complete itself. So I am going to press IC and when I press tab, it is completing my ecoform. Again CA, then tab, then cavity. Again CA, then tab, then cavity. So I think here many people have made mistake because after this last cavity, there is a space, PIPA. So in previous tutorial, what you guys used to do was you would put here dot and this dot represented current directory. Now instead of dot, if I put pipe, then it is going to copy this cavity file. But after copying, it is going to rename it as pipe. So now if I press enter and do LS, I will have a file named pipe. Got it? I think this is the mistake that those guys who were having trouble or said that cavity pipe is not found. They had this problem. Actually, we need to copy and replicate cavity as pipe. Yeah, as a pipe. That was the thing. Okay, actually we thought already in tutorial itself, cavity pipe is there. Okay. Now I am going to go to my pipe and what I am going to do is I am going to MB. MB stands for move. So I am just going to rename my 0, 0 pipe because if it is there, then it may create some problem. That's right. While opening parallel. So I just, sorry. Oh, I'm already inside pipe. So I don't need to do pipe. I think most people also did the same mistake. Instead, what I did. So I'm already inside pipe. This is why I don't need to give this pipe. Yeah. So what I'm going to do MB, 0 and then 0 dot oric. So this would rename my LS. Previously it was 0. Now it is 0 dot oric. It has changed its name. Now I'm going to type upon my block list. I'm going to use notepad for that. And I'm going to press enter. So I have already downloaded here the pipe and I'm going to copy all this. So this notepad file where we'll get this pipe notepad. So this notepad file you can get at your spoken to your website. Okay. So, so here and this spoken to your website. If you click here, the code file will download. Okay. Okay. Okay. Okay. So where was I? I just copied it. Right. And I had a notepad. Okay. This is my block. I'm going to copy my pipe. I just copied it. And here from here, I'm going to paste it. And I'm going to save it. So what are these vertices and how what are these blocks and edges? You can refer to spoken tutorial for that. I'm going to close this thing. And now when I do block miss, my block miss is done. Now let's see the result. Again, same procedure to see the result. Now if I do LS, it will create a result. File in my folder. I'm going to open my folder using X2.exe then dot. Now I'll give it. Okay. This is my pipe. So this is just a pipe, but you are not able to see the messes to see the messes. Go here in the surface, click here and select surface with edges. Now you can see the geometry how the division is done. This time this is a 3D geometry, which is why you are getting mess even in the Z direction. You can see the division in the mess. And this is the X and Y. Yeah. You can see the how the circular mess is being done. I think we have how many blocks? Five blocks, right? One. Then we have one block over here. So we have four blocks for the periphery and one block over here. If you want to visualize the block, you can do so by using paraform test block. This may or may not work on your double SL because this requires graphical interference to be enabled. So if you have Windows 11, this will work. So when I click on the flag, so this is the block that was used. So as you can see there are five blocks. This is the first block. And one, two, three, four. And these are the vertices that was used in the block mess file. So we have come to the end of this tutorial. And so even if you guys, some of you guys may have problem. You can again go to the same spoken tutorial website and then do it in your leisure time. And if you have problem, you can write us to our mail. We'll be happy to solve your problem.
