BC for a permeable internal wall
 

Hi,
is it possible to define such a BC for an internal wall (permeable to thewhole current)?
Or is it possible to merge the internal wall with the internal mesh so that it is just no wall anymore?

I am thankful for any help!

Well should not you use InletOutlet .

InletOutlet didn't seem to work, maybe I will give it another try...

Hello have you tried tutorial case on Porosity.
incompressible/porousSimpleFoam

specially the folder in anyCase/constant/porousZones file.

Have a look in it.

Hi kid,
my porous zone is fine, my problem is just the internal wall (unfortunately it needs to be there).

Hi,
Have you tried "empty " type BC.

Thanks for the reply!

I think I solved it with cyclic.
In my case the "internalWall" had a copy "internalWall_BACK" and with a cyclic connection everything is fine.
