Hi Mr.Jacobson and waves2foamers,

I am trying to simulate a porous Wave breaker and after successfully simulate a vertical wave breaker and a vertical porous wave breaker, I advanced to the next step; a porous wavebreaker with a certain steepness .But when I try this I qet problems at the interface of the porous and non-porous region. Right at the beginning of the simulation ( when the wave is generated ) I get some turbulences and strange particle movements at the interface face between the two regions, and this water displacement creates small waves in the opposite direction and the water fractions are being transported to the top of the wave breaker and through the air to the inlet.

I used the same configuration for the vertical porous wave breaker and for the inclined one and i am getting this strange behavior.
I dont know if it is a Meshing problem maybe I need to refine the zone at the interface when i introduce a steepness, or is there a conservation of mass problem?

someone experienced something like this and have some advices or ideas for this problem?

I'm using OpenFoam 2.2.2, and a Mesh with only rectangles and created with Gmsh

greeting everybody
