Dear All,
I am facing problem while running rhoPorousSimpleFoam solver in OpenFoam 2.0.x. I am trying to simulate pressure driven flows (Pressure is fixed boundary condition at inlet and outlet) in a simple pipe with porous zone. The K-Epsilon turbulence model is used. The solver is oscillating with higher values of epsilon on boundary. I am also facing problem in defining Porous media. If some one have some document regarding to that please send to me.
In some cases it runs by making so many changes in relaxation parameters etc. But the results are not validated, especially the pressure drop across the porous media both for isotropic and anisotropic cases. I am copying below the porous zone file defined for isotropic(homogeneous) porous media.
