Simulation won't run with k-omega model

Hi everyone!
I'm doing a simulation regarding the external aerodynamics of a wheel, I've tried different meshes in the past and I've rarely had this problem, the simulation that I'm running now works with other RANS turbolence models, with a segregated solver, (converge with K-eps) but won't even start with the k-omega, the program report a a floating point exception (Divide by zero) I've left the standard initial condition (beside the velocity=inlet velocity) untouched, the mesh seems good (no invalid cells, polyhedral mesh with about 15 prism layers, Y+ <1 all over the body), and I've try to run either with an initial condition given by the k-e simulation and without. Can you give me an advice to resolve this problem? thanks Best Regards Matthew |
