I have filter model which i did cfd analysis in both laminar and free and porous media flow .
The red marked part (attached below) is rectangular plate which acts like a interior wall where the air-flow mixture after entering through the inlet hits the rectangular plate and diverts into different flow direction.
(Note :The air flow mixture doesn't go into the rectangular plate ,the plate is kept for diverting the flow into directions ).
In laminar physics i have given interior wall option but when coming to the free and porous media flow there is no interior wall option so i tried wall and gave slip but there is no use and also the whole plate is not selecting only the edge is been selecting don't know why ?
So what should i do know ?
please suggest me
Thanks in advance
Regards
The comsol model is attached below (sep10)
The picture which shows the plate is also attached below(1234.jpg)

Hi,
You can use laminar flow domain and enable porous media as a sub-domain within that (by clicking one of the check boxes). With that you'll be able to use all the attributes of the laminar flow domain within your porous media sub-domain. Hope that helps.
