Hi there,

I would like to implement a transpiration boundary condition in SU2 for simulating blowing/suction from a solid permeable surface of an airfoil, for instance.

What I exactly mean with transpiration (or permeability) boundary condition is practically a solid wall, where the velocity components tangential to the wall are zero, while a nonzero velocity is allowed in the wall-normal direction. In pratice, this should be something like the already available subsonic BC_Inlet boundary condition with specified flow direction and mass flow, with the only difference that the wall-parallel velocity components should be aware that there is a wall. This is at the moment not the case.

Has anyone experience on this or an idea on how to formulate this in SU2?

I have been trying to merge the inlet boundary condition and the (for instance) isothermal wall boundary condition but without success at the moment.
