can you please why the permeability values are the same for air and water? as you explain that the porosity value is the same (0.7). The governing equations for mass and momentum conservation do not include the porosity term unless you select the physical velocity formulation but the flow is characterized only by the permeability that you define. Thank you

can you share the geometry file?
