Hello,
I have been working on the three-dimensional cavity flow problem for a while. The inner walls of the cavity normally have the "wall" boundary condition. I want to make the aft wall of the cavity porous. How can I do this? Can "Porous media" fulfill my request? I have marked the surface that I want to define as permeable with red below. thx in advance.. |

I didn't understand the model: the aft wall completely blocks the flow there.
How could that wall be porous in a way that flow can advect further downstream?

yes, modelling such porosity is possible.
have a look at the below: porousBafflePressure explicitPorositySource interRegionExplicitPorositySource directionalPressureGradientExplicitSource porousSimpleFoam rhoPorousSimpleFoam interIsoFoam
