Hi everyone,
I want to simulate an aerodynamic problem with a porous media model, and I am facing different problems in order to do it:
-
Impossibility to upload more than one geometry in the same project: as I understood after contacting the support team, if I want to generate different regions inside my model (i.e. cellZones for porous regions) I can just start from multi-solid step file, although snappyHexMesh starts always from a triangulated surface. For this reason, I think it would be nice the possibility to import different STL, as it happens in snappyHexMesh. If I am wrong or there are other solutions, please give me a reply.
-
Having not the chance to create a multi-body step file, I generated the mesh externally in OpenFOAM (creating cellZones to model porousMedia from STL). During the setup of the simulation I noticed that there is no porous model for incompressible solver. Is there a reason for that? Is the solver porousSimpleFoam not implemented in the platform?
-
In order to simulate it, I switched to compressible solver, where it’s possible to model porous regions. But again I got stuck, because I cannot apply the model to the already generated cellZones. The only option is to create a cartesianBox in order to select a sub-domain. Unfortunately I cannot use this option, because my sub-domain is not a cartesian box. Again, is there a way to solve this issue?
Thank you very much.
Regards,
Daniele
