My aim is to set cyclic boundaries to meshes created with snappyHexMesh, by means of createPatch utility.
The problem arises when patches to be joined (say inlet and outlet of a pipe) have different number of faces, which is a result of the mesh: createPatch gives what follows: --> FOAM Serious Error : From function cyclicPolyPatch: ![]() in file meshes/polyMesh/polyPatches/constraint/cyclic/cyclicPolyPatch.C at line 1383 Patch ![]() Perhaps your faces do not match? The obj files written contain the current match. Continuing with incorrect face ordering from now on! --> FOAM FATAL ERROR: For patch inlet_cyclic there are 7269 face centres, for the neighbour patch outlet_cyclic there are 7398 From function cyclicPolyPatch::calcTransforms() in file meshes/polyMesh/polyPatches/constraint/cyclic/cyclicPolyPatch.C at line 160. FOAM exiting Does anyone know how to proceed in such a case? thanks |

ok,
the answer was: use cyclicAMI conditions ----> http://www.cfd-online.com/Forums/ope...ber-faces.html |
