Help with Turbulence Divergence in CCM+

Dan

Hi all,

I'm running a ship simulation, which requires several thousand iterations to develop the wave pattern and converge the drag forces. My model seems to run fine for the first 5000 or so iterations, after which the turbulence models begin to blow up. The residuals go quite high, but the model doesn't diverge (yet!) any ideas what could be happening?

It is a time accurate simulation, VOF solver, k-eps turb, and incompressible.
