How to implement a 2D FW-H permeable surface in a 2D case?

[chancesFOAM]

Hi! I have some questions about the STL file in monopoly3D/constant/triSurface:

1. Is it created by some modeling software like Catia or proE?
2. How can I implement it in a 2D case in openfoam?
   Thanks!

1. Yes, it is created using SALOME package
2. Just make piece of STL, which corresponds to the depth of 2D computational domain in OpenFOAM

Hi Lawrence,

If I am not wrong, Openfoam doesn't have the theoretical 2D simulation. It will give a depth value in the third direction, so we need set dRef in libacoustics for the 2D case. You can check the depth of your 2D case in constant/polyMesh/points.
