Good morning everybody,
I nGood morning everybody,
I need help with a simpleFoam case, any start follows a interuption with time step continuity errors (log file below) and I have no idea why I got this error???!!!! My checkMesh are Ok, and any changes on nNonOrthogonalCorrectors factors an relactionFactors are pointless (nNonOrthogonalCorrectors from 0 up to 5 andt the relaxationFactors (pressur) 0.5 down to 0.1 (for the other 0.7-0.5)). But nothing change any the same error, but on a other iteration step . A last word to the controlDict dt=1/startTime 0/endTime 1000 . Hope of any advice, Thx // * * * * * * * * * * * * * * * * * * * * * * * * Create time Create polyMesh for time = constant Time = constant Mesh stats points: 210406 faces: 1550050 internal faces: 1440066 cells: 697760 boundary patches: 3 point zones: 0 face zones: 0 cell zones: 0 Number of cells of each type: hexahedra: 0 prisms: 189689 wedges: 0 pyramids: 9387 tet wedges: 0 tetrahedra: 498684 polyhedra: 0 Checking topology...
