H3PO is on a distinguished road
Hello, I'm new with OpenFoam, and I need to simulate a Air Flow inside of tubular cavity to check how it behaves. So, I started with this tutorial: https://www.youtube.com/watch?v=ObsFQUiVi1U and later I tried to do the same with a solid cilinder. I have created the mesh, but when i vusualize this with paraView, it observe that the internal Mesh is a cube (and the cilinder is inside), whears in the tutorial has the shape of the objet. I attach you some images about it.

If someone could help me with this or indicate a better guide i will than her.

It is usually helpful to also post the necessary files. Is it possible that you set "locationInMesh" outside of your geometry?

I think that is it. I have tried to solve but I didn't get it. Can you give me some advice on how to get the center of my object?


Thanks for your help!

IIRC the location should be somewhere inside. It does not need to be in the center.

Thanks guys, I have managed to create the internalMesh successfully.



Now I want to simulate my final object. It is a bit more complex. So, I don't know how to obtain a surface from the solid, Is there any software to obtain this?

There is a lot of information regarding preparing stl files for SHM in this forum and a video series at https://holzmann-cfd.com using Salome and blender.
