Hi,
If I want to run a laminar flow problem with simpleFoam, what kind of parameters I need to provide. It seems to require wallFunction. Here is the erro message
--> FOAM FATAL IO ERROR : keyword wallFunctionCoeffs is undefined in dictionary ....

You don't need to provide any parameters for the laminar "turbulence model" but the base class will read the wall-function parameters but they won't be used.

Thanks,
So, in the file of /constant/turbulenceProperties,
once I set:
turbulenceModel laminar;
turbulence off;
it REALLY solve the laminar problem.

Yes
