Porosity model not found for pisoFoam; works fine for simpleFoam
 
Hello all. I have a DES solution I am running using pisoFoam, in which I get the following error:

Code:
--> FOAM Warning :
From function void Foam::forces::calcForcesMoment()
in file forces/forces.C at line 917
Porosity effects requested, but no porosity models found in the database
forceCoeffs forcesAll output:
This error is a bit confusing as the fvOptions file is the same as it was for the steady state simpleFoam solution (which did not throw any errors.)

Are porous media not supported by pisoFoam? Or does the inclusion of porous forces simply not work with pisoFoam?

Take a look at the tutorial I just wrote

Greetings to all!

ssss' solution should work.

But to answer to another part of aerogt3's question: pisoFoam in OpenFOAM 2.3 and 2.2 was not modified to include support for the "fvOptions" feature. The closest solver you can find is pimpleFoam, which is essentially a PISO-SIMPLE hybrid solver, which (allegedly) is better than pisoFoam.

If you still want to add the "fvOptions" feature to pisoFoam, compare the source code of the simpleFoam and/or pimpleFoam solvers in OpenFOAM 2.1 vs 2.2, to see how this feature can be added.

Best regards,
Bruno
