Rotational periodic Boundary condition
hi,
I need to use rotational periodic boundary condition for my model. I used 'cyclic' boundary condition for 2 planes and OF gave the following error. ---------------------------------- Create time Create mesh for time = 0 face 0 area does not match neighbour 1021 by 123.634% -- possible face ordering problem. patch:SYM1 my area:3.13674e-06 neighbour area:1.32932e-05 matching tolerance:0.001 Mesh face:2900402 vertices:3((0.00766235 0.0434244 0) (0.00210264 0.0462494 0) (0.00291487 0.0469651 0)) Neighbour face:2901423 vertices:3((0.00390903 0.00637109 0) (0.00794004 0 0) (0.00376707 0 0)) Rerun with cyclic debug flag set for more information. From function cyclicPolyPatch::calcTransforms() in file meshes/polyMesh/polyPatches/constraint/cyclic/cyclicPolyPatch.C at line 180. FOAM exiting --------------------------------------------------- How can I improve my mesh to use cyclic boundary condition? Are there any other methods to define rotational periodic boundary condition? Thank You. Regards, Achinta |
Hi,
I tried to use 'wedge' boundary condition on 2 planes to define rotational periodic condition for my model. OF gave the following error. ------------------------ Create time Create mesh for time = 0 #0 Foam::error::printStack(Foam::Ostream&) in "/usr/logau/expsm/OpenFOAM/OpenFO AM-1.6/lib/linux64GccDPOpt/libOpenFOAM.so" #1 Foam::sigFpe::sigFpeHandler(int) in "/usr/logau/expsm/OpenFOAM/OpenFOAM-1.6/ lib/linux64GccDPOpt/libOpenFOAM.so" #2 ?? in "/lib64/libc.so.6" #3 Foam::wedgePolyPatch::initTransforms() in "/usr/logau/expsm/OpenFOAM/OpenFOA M-1.6/lib/linux64GccDPOpt/libOpenFOAM.so" #4 Foam::wedgePolyPatch::wedgePolyPatch(Foam::word const&, Foam::dictionary con st&, int, Foam::polyBoundaryMesh const&) in "/usr/logau/expsm/OpenFOAM/OpenFOAM- 1.6/lib/linux64GccDPOpt/libOpenFOAM.so" #5 Foam::polyPatch::adddictionaryConstructorToTable<F oam::wedgePolyPatch>::New( Foam::word const&, Foam::dictionary const&, int, Foam::polyBoundaryMesh const&) in "/usr/logau/expsm/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libOpenFOAM.so" #6 Foam::polyPatch::New(Foam::word const&, Foam::dictionary const&, int, Foam:: polyBoundaryMesh const&) in "/usr/logau/expsm/OpenFOAM/OpenFOAM-1.6/lib/linux64G ccDPOpt/libOpenFOAM.so" #7 Foam::polyBoundaryMesh::polyBoundaryMesh(Foam::IOo bject const&, Foam::polyMe sh const&) in "/usr/logau/expsm/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libOpe nFOAM.so" #8 Foam::polyMesh::polyMesh(Foam::IOobject const&) in "/usr/logau/expsm/OpenFOA M/OpenFOAM-1.6/lib/linux64GccDPOpt/libOpenFOAM.so" #9 Foam::fvMesh::fvMesh(Foam::IOobject const&) in "/usr/logau/expsm/OpenFOAM/Op enFOAM-1.6/lib/linux64GccDPOpt/libfiniteVolume.so" #10 main in "/usr/logau/expsm/OpenFOAM/OpenFOAM-1.6/applications/bin/linux64Gcc DPOpt/simpleFoam" #11 __libc_start_main in "/lib64/libc.so.6" #12 _start at /usr/src/packages/BUILD/glibc-2.9/csu/../sysdeps/x86_64/elf/start .S:116 Floating decimal point exception --------------------------------------------- What could be the reason?
