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.
