I'm using OpenFOAM-1.5-dev Ubuntu 9.04 64 bit.
I'm attempting to set up a rotating mesh, with a cylinder inside a block with a hole, just a little larger than the cylinder. (the cylinder is about 2M across and the gap is 0.5mm) See picture at end. When I run it, I get this error: ==================== From function void GGIInterpolation<MasterPatch, SlavePatch>::rescaleWeightingFactors() const in file /storage/software/OpenFOAM/OpenFOAM-1.5-dev/src/OpenFOAM/lnInclude/GGIInterpolationWeights.C at line 533 Uncovered faces found.

Does it have to do with the two meshes not lining up perfectly? I tried it with several different programs: turbDyMFoam - error and crash icoDyMFoam - error and crash IcoFoam error message, doesn't crash, good results. PotentialFoam error message, no crash, strange results. (velocity changes through ggi interface, like light through a lens.) traceback on the crash is: =================== Program received signal SIGSEGV, Segmentation fault.
