Default Problem with k-omega turbulence model

Dear experts,
when trying to simulate a "standard" free-surface flow situation with the k-omega turbulence model of FLOW-3D (v11.1), the following error occurs directly after preprocessing the simulation:

"fatal error, negative discriminant in quadratic solver 5.3174747E-01x^2 +x + NaN = 0.

Abnormal exit from solver"

The simulation stops afterwards. With the standard k-epsilon as well as with the RNG turbulence model, the simulation finishes without problems.

Do you have an idea how to solve the problem?
Thanks in advance and best regards
