Hi, CFD people! I need to specify a secondary boundary condition for my uds, but the boundary condition value relates to the boundary flow values such as u,v,w. While in pressure based segregated solver, those values could be accessed by using MACRO F_*, in density based solver using F_* results in "access violation". So, how can I get boundary face values in density based solver?

Thank you!

access to cell-center values and gradients to recover the values on the boundaries. it's the only way. Luca

Thanks a lot!

Hi Luca!
Do you know any reference about the interpolation from cell center to face center on the boundary? I want to access wall pressure in density based solver and face the same problem (F_P didn't work).
