On some walls of my model, I want the walls to be "non-slip" and "non-flux" for the continuous phase, however, I want them to be outlet boundary for the dispersed phase.

Such cases appear when the dispersed phase is absorbed or decomposed on the wall.

However, when I was trying the "dispersed phase boundary condition" option in the those walls, I failed to find a third-type condition, nor I did not succeed trying a "flux" condition.

Even when I specify a "flux" boundary condition for the dispersed phase, none of the flux values (including 0) works.

It always says "Undefined variables"...blabla..."failed to evaluate comp1.mm.Nphid" blabla

Does it ring a bell to anybody?
