Error when I add a porous region

siara817 · May 30, 2012, 05:31

I specified some boundaries as a porous region. But when I try to run the simulation, I get an error. The error says " invalid fvregion".
Does anyone have any idea about the error?
Thanks in advance

I'm a little confusing about that "you set boundaries as porous region". Only the whole region can be difined as a porous region.
I guess you set the boundary as porous baffle, right?
If you did that, there is a restriction that the regions between this boundary should be in the same continuum, which means they should share the same "physica".

The problem was caused by the mesher. It was meshing both regions simultaneusly, so the second region was removed by the mesher. To solve the problem, I clicked the item Continua/Mesh and in the mesh properties I ticked the item per-region meshing. The problem was solved.
