Question about permeable B.C. for baffle
 

Dear foamers,

Greetings,

Since I am simulating LPT with porous media(explicitly). The particle will penetrate the porous media because it does not have suitable interaction between particle and porous source term.

My goal is to letting the particle rebounds from the porous but "permeable", more clearly, identical with internal faces. Therefore I created a baffle which surrounds the porous source hence I can specify patchInteraction.

However, I am not sure which B.C. type is suitable for this baffle in p, U, Yi field?

Thanks in advance,
Rick
