OpenFOAM v5 --> foam-extend 3.2

Hi,
I have created a mesh using blockmesh on OF v5 and performed some simulations fine with it. I am now using foam-extend 3.2 to run some different simulations with the same mesh. When I want to build the mesh I receive face ordering errors, which did not happen when using OF v5. Has anyone else experienced this problem? If I just copy over the polymesh directory from the OF v5 case to the foam-extend 3.2 case, I get problems with cyclic boundary conditions when trying run the simulation. Again, no problems when using OF v5. The error I receive about cyclic boundary conditions is below: Code:
face 82249 area does not match neighbour 164499 by 35.2941% -- possible face ordering problem. patch:front my area:3.71429e-08 neighbour area:5.30612e-08 matching tolerance:0.001 Mesh face:19723349 vertices:4((0.0245 0.00252571 -0.018) (0.0245 0.0026 -0.018) (0.025 0.0026 -0.018) (0.025 0.00252571 -0.018)) Neighbour face:19805599 vertices:4((0.499286 0.00512571 -0.018) (0.499286 0.0052 -0.018) (0.5 0.0052 -0.018) (0.5 0.00512571 -0.018)) Other errors also exist, only the largest is reported. Please rerun with cyclic debug flag set for more information. From function cyclicPolyPatch::calcTransforms() in file meshes/polyMesh/polyPatches/constraint/cyclic/cyclicPolyPatch.C at line 293. |

If it's a blockMesh mesh, then your problem isn't a problem at all. Simply run blockMesh of your foam-extend installation to re-create your mesh.
OpenFOAM-5 and foam-extend-3.2 most probably produce mesh-files using slightly different format. However, both should be able to create a mesh from a blockMeshDict file. |

When running the blockMesh command using foam-extendn 3.2 I receive a face ordering error like the one below. This doesn't happen when using OF 5
Code:
Creating curved edges Creating topology blocks Creating topology patches Creating block mesh topology --> FOAM FATAL ERROR: face 0 in patch 0 does not have neighbour cell face: 4(16 17 37 38) From function polyMesh::facePatchFaceCells(const faceList& patchFaces,const labelListList& pointCells,const faceListList& cellsFaceShapes,const label patchID) in file meshes/polyMesh/polyMeshFromShapeMesh.C at line 124.

I am having your same error. Did you manage to solve it? It works in the latest version of openfoam, but in foam-extend-5.0 it gives me that same error. |
