I ran into a "Segmentation Fault" that's preventing me from running pimpleDyMFoam. I'm not trying to run in parallel.

My case uses a pretty coarse grid that consists of a 1-cell high square with a round hole, which has a round 1-cell high disc in it that has a blade shaped object in the middle. It's a ggi setup, just a test to get a case running then I can change my geometry to my turbine.

I don't get any error message other than "Segmentation Fault":

Segmentation fault

Any ideas? Is it just that my mesh is THAT bad (coarse)?
