Converting mesh from Icem CFD to OpenFoam
 

Hello,

I have a problem to import a mesh-file (*.msh), which I created in Ansys Icem CFD, to OpenFoam.

Basically, the mesh describes two circular tubes sticked together like a T-Junction.
When I use the "mshToFoam <*.msh-file>"-command, I receive the following ERROR:

I have no idea why I receive the "Segmentation fault"-Error, which mistake causes the Error OR where I have to search for the mistake.

I already checked the memory, and there should be enough memory to handle this conversion. This should not be the reason.

I found this following Error-description which could have the same origin:
http://www.openfoam.com/mantisbt/vie...d=104#bugnotes

But honestly, it doesn't help me to fix the Problem.


Does somebody have an idea what to do to find the mistake resp. solve the problem? Perhaps somebody had this problem before and knows how to fix it?
I really need to import this mesh into OpenFoam and run simulations ...!

Many thx

try to use "fluent3DMeshToFoam meshname.msh"

ok, i got it.

there are differences between *.msh-files, although the ending ".msh" is the same.

in my case i used the "FluentV6x"_solver to export the mesh from Ansys, and in OF i used "fluentMeshToFoam" (or as you told me: "fluent3DMeshToFoam") to import the mesh.

following this export/import-procedure, it was finally possible to import the mesh in OF and run simulations on it.

Thank you very much for your help.
