Difference between fluentMeshToFoam and Fluent3DMeshToFoam
 
Hello all. I am new here and I'd like to greet you all.

I have been working with OpenFOAM for the last couple of months. I have set up a few simple cases and parallel processing and I am getting deeper into it.

I have been wondering what is the difference between fluentMeshToFoam and fluent3DMeshToFoam. As far as I can see, there is not any significant difference. Is this correct? In which cases should one use one command or the other?

Thank you.

fluentMeshToFoam is the old code. It can handle 2D Fluent meshes but struggles with some 3D meshes (for example, meshes with hanging nodes)
fluent3DMeshToFoam is newer. Can handle only 3D meshes, but it does this much better than the old one. If you have a 3D mesh, this has to be preferred, in my opinion.

Hope this helps,
Francesco

How to use fluentMeshToFoam or fluent3dMeshToFoam?
 
Hello guys,

How can I use this function? when I write "fluentMeshToFoam <e.g. myFileName>" it says "bash: syntax error near unexpected token `newline' " .
Is there any package to be installed? If yes, how?

Thanks in advance.

Solved
 
I wrote the incorrect syntax, it should be like this:

"fluent3DMeshToFoam filename.msh"

Also, for cyclic patches fluent3dMeshToFoam writes the patches in the ordered way but fluentMeshToFoam does not. I had experienced this in v2.0. Please verify if this behavior is still the same.
