local coordinate system for porousZone
1 Attachment(s)
Hello FOAMers,
I am working with porous media, simulating the resin flow in laminate systems. In my case the permeability is anisotropic, so depending on the direction of the reinforcement. So far I was able to define some porousZones with different coordinate systems. But if I have a geometry with radii, I need to define a local coordinate system for each cell (shown in the attachment) in order to define the permeabilities kx, ky, (kz, later for 3d problems). At the moment, I could only define the local coordinate sytems manually in the meshing preprocessor, but that would be time consuming for larger geometries. So the objective is to define a local coordinate system for each cell automatically and store it in the "/constant/porousZone" file. Note: the y1, y2, ..., yn axis should be perpendicular to the nearest wall and the x1, x2, ..., xn axis is tangential to the nearest wall. Up to now I could not find any tool in OpenFOAM solving exactly that problem and I am unfortunatly not a Pro in programming C++. Does anyone have an idea about it? Thanks in advance for any advice. |
