how to access each cell of a face? (user fortran)

Katariina

Hello all,

I have a problem of accessing face information. (CFX11, user fortran)

I am generating a general momentum source for a 3D-subdomain with user fortran. I need the normal vector components of the bottom face cells of the subdomain (each cell separately); each cell of the subdomain will use the information of the bottom face cell "below" it. I would like to use a Junction Box routine at the beginning of each iteration and store the bottom face normal vector components then for the actual user CEL routine. The code should work also in a parallel run.

USER_GET_GVAR (with area_x/y/z as USER_OPER) gives the integrated normal area vector components of the whole face, right? Not each cell separately? But if it does give the information for each cell separately then how do I find the number of cells (or the NLOC)?

I can't find a way to do this so if someone could help me I would be most grateful!!
