Hi everyone,

I am running a flat plate Turbulent BL using simpleFoam and i get the following error. Could anyone help me out with this? Thanks!

Create time

Create mesh for time = 0

Reading field p

Reading field U

Reading/calculating face flux field phi

Selecting incompressible transport model Newtonian
Selecting RAS turbulence model kOmegaSST
kOmegaSSTCoeffs
{
alphaK1 0.85;
alphaK2 1;
alphaOmega1 0.5;
alphaOmega2 0.856;
gamma1 0.555556;
gamma2 0.44;
beta1 0.075;
beta2 0.0828;
betaStar 0.09;
a1 0.31;
b1 1;
c1 10;
F3 false;
}

No finite volume options present


SIMPLE: no convergence criteria found. Calculations will run for 100000 steps.

It appears that you may be missing parts of the files within the system/ directory. Posting the controlDict, fvSchemes, and fvSolution files may prove helpful.
