I'm using 68185c76 on Debian GNU/Linux 8 (jessie). I believe I found some problems with the overset mesh implementation.
dynamicOversetFvMesh.C:96 Pstream::exchange<labelList, label>(remoteFaceCells, sendCells); Neither remoteFaceCells nor sendCells are used after this exchange. I can't see its purpose. Results are not affected when I comment it out.
Parallelisation problem. The overSimpleFoam tutorial (aerofoil) converges in serial, but fails to converge in parallel. May be related to above. Mind you, this may be a red herring, because I get this warning: --> FOAM Warning : From function bool Foam::oversetPolyPatch::master() const in file oversetPolyPatch/oversetPolyPatch.C at line 149 The master overset patch is not the first patch. Generally the first patch should be an overset patch to guarantee consistent operation.
