Hello All, I've been using
 
Hello All,

I've been using OF for about 2 years for aerodynamics, but I always used Salome to create the meshes (by unv conversion).

Now I'm playing with snappyHexMesh (great tool), and already created some meshes.

Since I also use ANSYS-CFX for comparison, I'm trying to convert the created mesh for it, by using the foamMeshToFluent application, and receiving this error message:

I tried anyway to convert in CFX, but it complains about polyhedral cells (not suported).

Does anyone know how can I solve this issue?

My intention is to concentrate all the process in OF utilities.

Thanks in advance.

Hello again,

As an alternative way, I thought about using the tetDecomposition utility to get a pure tet mesh. It is in the User Guide, but I cannot find in the command line.

Does anyone know where is the application (if it changed the name, for example) ?

Best Regards,

Hi, Paulo Rocha,

Did you find the tetDecomposition tool?
I also cannot find it. Please let me know if you know the solution of this.

Hi Paulo,

Did you manage to use foamMeshToFluent? I am trying to do the same thing and I get the same error
