I am having my fluent model with rotating behavior. While having 1000rpm, the simulation is going smooth and correct. While having lower rmp (500rpm), floating error occurs after few iteration. Does anyone know why is it so and how to solve it. It is urgent. Please help.

hi,
check your initial value and if you have zero initial value change them or use double precision method.
i hope u reach to your purpose if you do so.
