Hi, If I want to run a lamina
 

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
 

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 /c
 

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