UDS Boundary conditions

Max Perrotta

Hi! My problem is to set UDS boundary conditions, which depend on the results of iterations in a steady problem, on a planar interface between a fluid and a solid region. My UDS is vapor mass fraction in humid air flowing on the solid wall. The problem is to impose the saturation value of mass fraction corresponding to the wall temperature at any single point (the saturation in ensured everywhere on the wall surface). So I need to update my UDS boundary conditions after each iteration of energy equation solution, that gives me the updated values of temperature. I tried to use a DEFINE_ADJUST macro but it doesn't work. It seems to me that the values computed by the macro at each iteration are overwritten by the boundary conditions that I initially set on the surface using the GUI "Boundary conditions" panel. How can I solve this problem? Every suggestion is appreciated.

Regards
