Hi everyone,

I am working on external laminar flow over model with a velocity of 10 m/s using pisoFoam>ras using snappyHexMesh. The mesh part has been done but I am unable to simulate the flow. On running pisoFoam solver, it is giving the following error:

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 turbulence model type RASModel
Selecting RAS turbulence model kEpsilon

Starting time loop

Time = 0.005

Courant Number mean: 0.166758 max: 7.5028

Please suggest how should I proceed to rectify this error.

RodriguezFatz will become famous soon enough
Can you post the boundary + initial conditions and the fvSolution file?
