Default compressed porous media, need help
Posts: n/a
I have a 2D cylinder with a moving top wall (only moving down) and a solid stationary bottom wall, the 2 walls on the sides are pressure outlet boundary conditions. in the interior of the cylinder, I want to have a porous media (can I also add fluid in the porous media). As the cylinder comes down, the porosity should should decrease (does fluent do this automatically internally or do I have to define a UDF), as a result fluid comes out through the presure outlet boundary conditions. I have been reading fluent tutorials and so on. Can this be done and can someone help me with this.

Thank you
