hello
i am new to ansys.
I'm simulating flow in a direct perfusion bioreactor. (Shown in picture below)
The middle zone is scaffold (a porous solid zone which fluid will pass through.)
cross section of perfusion bioreactor front view:


front view of perfusion bioreactor :


my question is :
How should i represent the porous zone in my geometry?
Is it enough to just split the body by to horizontal plane (as shown in picture) ,and i can set the splited zone as a porous zone in solving process? or i should represent my porous zone with a solid in spaceclaim?

regards
