Hi everyone,

I'm currently trying to import a mesh created in abaqus into OpenFOAM, by using matlab scripts and the abaqus .inp file to create a fluent .msh file. From there I was planning to use fluentMeshToFoam.

However, using fluentMeshToFoam gives the following error:

[michael@semar-linnex3 meshtest3]$ fluentMeshToFoam output.msh

What exactly does this error mean? It's apparent that something's wrong with the .msh file, and I've tried looking for something indicating 0 is designated as having element 2717 as owner, but couldn't find anything. The output.msh file is in the link below:

Any help is appreciated!

Turns out there were a couple of boundary faces (in a different part of the mesh) that were misidentified as internal faces, and when that was fixed, the mesh loads just fine.

I'm still not sure why this error message appeared; it seems unrelated to what fixed the mesh. Oh well, it works now at least!
