Great tutorial!

Well done

In order to have a good approach of this video, put the speed in 1.5 or more.

I have a simple question. I see that you have lines inside the computational domine that are not boundary conditions (with the final purpose of make easier the meshing because you have more control over the numer of nodes in the lines); you only classify as phisycal groups the boundary conditions and when import the mesh in the CFD program, these lines dissapear and you have the mesh with the boundaries and no more...

Thanks sir for your comment. I think you answered your question, it is to make easier and control the meshing, especially around the cylinder.

Thanks a lot. But wh without sound???

nice job! thank you very much.. I just wonder whether the orientation of the circle will affect the result or not? And is there any attention we need to pay for the orientation?

thanks for your comment, what do you mean by the orientation of the circle?

@@rhmtutorial I mean, for example, in blockMesh we need to plot the surface in a clockwise direction. So do we need to do the same in Gmsh? Thank you very much.

Hi rHm, I am trying to follow up your tutorial but everytime I click on 'Volume' I am not able to generate the mesh. Do you know how to fix this? Thanks!

Hi Antoine, did you mean the physical groups (volumes)?

Hi @@rhmtutorial, yeah at 32:41 when I tried to generate the Volume. Once I clicked on the volume option my screen freezes or I got a segmentation error, thanks really

Hi @@rhmtutorial , I tried and it doesn"t work. May I paste my .msh file here ? Could you try to check if the volume option works for you? Thanks

Hi rHM, Thank you for the nice tutorial. Since it is a complex procedure, I would request you to make available the final .geo file that you prepared so that we can retrace your steps directly through the scripts. Thank you!

Thank you for watching the video, unfortunately i don't have the file .geo, it's better to repeat the tutorial step by step and look after every step to the script to learn faster. For any question write me on the e-mail.

@@rhmtutorial Thank you the reply. The difficulty in repeating the tutorial is that after a point, there are too many physical surfaces and points to manipulate that it is not clear from the video what exactly you are clicking on. Also, the script on the video is not very legible. As you may notice, this is the only elaborate GMSH tutorial for this kind of problem available on the youtube. I am sure that if you provide a .geo file with this tutorial, not only will your viewership go up, but also it would benefit a lot of people. Also, where do you I find your email id?

Please bro teach me do the simulation after the mesh.
