porousSimpleFoam - keyword wallDist undefined

Hi everyone,

I am working on a model with a porous net, which should be simulated using the porousSimpleFoam solver.

When trying to run it, simulation stops shortly after having started and displays following error message:

Code:

Selecting incompressible transport model Newtonian

Selecting turbulence model type RAS

Selecting RAS turbulence model kOmegaSST

[3] 

[3] 

[3] --> FOAM FATAL IO ERROR: 

[3] keyword wallDist is undefined in dictionary "/home/nicolas/OpenFOAM/nicolas-3.0.1/run/sim_multipor_mapped_test1/processor3/system/fvSchemes"

FOAM parallel run exiting

I do not see where in fvSchemes wallDist is needed... Does anyone have experience using this solver?

Thanks in advance

Hi,

This needs to be added to the end of fvSchemes.

Code:

wallDist

{

    method meshWave;

}

Next time if you are in doubt, look at one of the tutorials:

Code:

grep -r wallDist $FOAM_TUTORIALS

to find examples.

Regards,
Tom

It works, thanks a lot!

I was adapting a case made with v2.3.0 to work in v3.0.1, that's probably why this little detail slipped...

Hi,

why this keyword now is necessary?

Thanks

I am not 100% sure, but I believe the change was due to the method not being hardcoded anymore in the most recent versions of OpenFOAM. These kind of changes happen between major version changes and are usually described in release notes.

what does walldist mean and the best value for walldist is what?
