I am trying to validate a work which involves multiphase flow along with a porous media. I am very close to the validation but a problem is occurring for which i need certain help from you guys.
Actually after I had initialized and patched the fluid flow domain with 0.185 solid volume fraction the problem initialization is exactly similar to that given in the paper. But when I am running the solution my porous media is not being recognized i.e whole of the particles phase red strip is moving down and eventually going into porous media zone.
I am attaching a reference paper part of the work which i am trying to validate and also attaching the result which i am getting.

Image 102 is the work which I am trying to validate. Image 104 (1) and 104 (2) are of my solution.
