Ankur Kaushik is on a distinguished road
I'm trying to model 3D flow around a bridge pier using OpenFOAM module simpleFoam. What should be the values of k and omega at walls and the free surface? The boundary condition type at the free surface is the symmetry boundary condition.

Bloerb will become famous soon enough
At symmetry boundaries you don't need a value. It is computed. Hence the value you input is only used at the first time step. Simply choose something in the range you expect.
