I'm new with OpenFOAM... and have this error when convert a Fluent mesh to Open Foam...

Hi bola,
Before you run fluentMeshToFoam, make sure that you have a controlDict file in your <root>/<case>/system/ folder. copy thye control dict from one of the tutorial cases. Also try running a few example cases first. |

Hi,
I need to know if my mesh is correct (converted by fluent3DMeshToFoam). With Fluent CFD code I get the correct comportment (the same mesh), but with openFoam the courant number increase from 1e-3 to one after 100 iterations, and I get strange comportment. I use 4 non-orthogonal correctors. Thank you a lot for help a check mesh gives me: Time = constant Mesh stats points: 314704 edges: 1088715 faces: 1277556 internal faces: 1211202 cells: 492171 boundary patches: 13 point zones: 0 face zones: 0 cell zones: 2 Number of cells of each type: hexahedra: 257595 prisms: 0 wedges: 0 pyramids: 4884 tet wedges: 0 tetrahedra: 229692 polyhedra: 0 Checking topology...
