ERROR 10364 - NaN returned from internal turbulence module

Description

The turbulence module returned a NaN (not-a-number) value for the eddy viscosity or diffusivity. This indicates an instability within the vertical turbulence closure scheme during the simulation.

Suggestions

Review the turbulence model settings and check the model for numerically extreme conditions such as very large velocities or sharp gradients.
