Guys,

I want to use OF to analyze marine propellers and, following the "propeller" tutorial, I have created my case test. I use shm to do the meshing, followed by topoSet, createBaffles and pimpleDyMFoam.
When I run createBaffles, I have a warning that some cells are set in two different zones, but I new that because the propeller hub intersects the inlet patch.
I'm using dynamicMesh to rotate the mesh as the tutorial, however, when I try to run pimpleDyMFoam, I get this log:

Any one has any idea what might be causing this problem? I have gone over and over through the input files and I just can't find the problem.

Did you change the dynamicMeshDict in your constant directory? I had the same problem because I left it as "innerCylinderSmall" when I was building my own case based on that tutorial.
