Is it possible to define the shape of holes in Porous media?

      Lets say I want a disc shaped porous medium with 3mm thickness and 15mm radius but with holes of a certain shape and size (lets say squares with 3mm^2 area)


      Possible?

      If you read up on the porous media functions you see it's a lumped model to mimic a pressure lost caused by "stuff" in the flow volume. So, I can calculate the effect of square, round or oval holes in a plate and get the same resistance coefficients depending on hole size & spacing. 


      Please read through the section of the manual: if you can't use the thin plate equations to determine a resistance coefficient you'll need a sub model.
