Hello,

I have created a Mesh in Salome pre-processing software and exported it into OpenFOAM using the ideasUnvToFoam process. I have designed it in 6 separate sections then built a compound mesh with all sections together, each defined by their respective group geometries such as inlet, outlet, etc.
However, I am trying to use the rhoPorousMRFSimpleFoam case with this mesh. When I load it up with all the various parameters, I get stuck when it asks for

--> FOAM FATAL ERROR:
cannot find porous cellZone Stone_1

From function Foam:orousZone:orousZone(const keyType&, const fvMesh&, const dictionary&)
in file cfdTools/general/porousMedia/porousZone.C at line 94.

The problem is when I've exported the Mesh from salome, no cellZones are created so I can't modify them for this case.
If someone could tell me how either to export the mesh from Salome to include cellZones or how to modify the porousZone input without the need for cellZones, I would be really grateful.

Thanks in advance

If anyone wants to know the answer of how to create a cellzone using Salome. Simply select the regions from the "Create Groups from Geometry" under the volume element. Add these in the Mesh section, then export.
