Hi all,

I created two meshes in ICEM and exported to fluent .msh format. After that I ran the fluent3DMeshToFoam app to create the OpenFOAM mesh. Until this everything is fine, but if I want to merge the meshes using the mergeMeshes utility, the program fails. I have 3M cells in inlet region as Master and 9M cells in rotor region.

Do you have any idea for the reason? Thanks in advance!

Here is the output of the process:

I "solved" the problem by using the most recent release of OF2.1.x.

Hi attesz

I have exactly the same problem as you. Unfortunately I have been using OF2.1.0. So do you have some other ideas?

I am using currently Openfoam version 2.0.x. I have got the same error. Did you find a solution for the merging error?
