Hi guys,
I'm using the k-epsilon and k-omega models in simpleFoam.

I would like to know the boundary conditions at the wall for an external flow.

At present I am using the following condition:

type omegaWallFunction;
value uniform 0;

But I am not sure about the correct value.
I have the same problem when using the k-epsilon model...

Thank you !

value uniform 0;
it is only place holder, it returns values base on internal calculation,
look in source code to see what function is used to evaluate it
