Pointers to wall adjacent cells in CFX 5

November 19, 2002, 03:43

Can somebody suggest how I can obtain the pointers to wall adjacent cells in CFX 5? Or give me some advise how I can put different sources of a passive scalar in the wall adjacent cells than in the cells in the main flow field. In CFX4 I solved this question via the FORTRAN subroutine "IPALL". Do I have to do this also via Fotran in CFX5 or can I make use of the CEL? Thanks

Can you set your additional variable source as a flux through the boundary (i.e., units/m^2)? If so then you can use a CEL expression or a CEL user fortran routine.

If you need a volumetric source to be applied in boundary control volumes then this will require special coding.

I need to put volumentric sources. What I want to do is to program my own wall-functions for my passive scalars. So who do I get the pointers to the wall adjacent cells? Cheers Fabian
