DEFINE_SOURCE
 

hi all

does anybody know how to apply the macro DEFINE_SOURCE to define mass source for the different phases in a multiphase model? How do I tell FLUENT if I want a wall to be sink for the primary phase only? Many thanks in advance.

in the boundary conditions panel select the fluid zone. On the bottom of panel you can select which phase you require. select set and define the source term

thanks Alec. By the way, have you done something similar before, i.e. simulating a separation process through a filter?
