engineFoam: unstable velocity field

Hello Foamers,
I'm trying to simulate combustion in a diesel engine, by copying our Kiva mesh to the combustion/engineFoam/kivaTest tutorial case. Our mesh does not contain the whole 360° cylinder, but a "piece of cake" with cyclic boundary. Mesh conversion runs just fine, but engineFoam can only compute crank angles from -180° to at most -178° before the velocity field at the center of the piston is getting very unstable and finally janafThermo gives the Fatal Error. Maybe just copying a cyclic mesh to the (non-cyclic) Tutorial Case isn't enough. Can anyone help me? Thanks in advance, Max Last edited by mmeyer; April 14, 2015 at 03:07.
