Spherical slice in Salome for OpenFOAM

I am trying to generate and mesh a slice of a spherical structure in Salome for an OpenFOAM simulation. I kinda managed to set it up, but I must have made some mistakes somewhere, since the converted unv produces some funky results.
What I did: - Create symmetry face and revolute ( and explode) - create NETGEN 1D2D submesh on symmetry face - use mesh revolution to create prisms from submesh that match the geometry - split pyramid into tetrahedra (pyramids cannot be exported through unv) - create groups through filters (that got kinda messy) - export unv and convert with ideasUnvToFoam checkMesh gave me a whole bunch of errors: Code:

Like, what do I do with the defaultFaces (set to empty and ignore?) and where does that crazy local non-orthogonality originate from? What are wrongly oriented faces? Would be very grateful for any help, this is how far my limited experience takes me Heres the study: http://www.file-upload.net/download-...lice2.hdf.html Oh and happy holidays ! |

I have still to solve my problem =/ Has noone encountered this before?
Can anyone think of a work-around? Like are there other, more appropriate meshing mechanisms? Could really use some help! EDIT: Solved. If anyone faces a similiar issue: There is a very useful Python script for Salome to OpenFOAM conversion: http://www.salome-platform.org/forum/forum_12/23863165 Last edited by Jakob1; January 11, 2014 at 07:03. |
