Default instability in fluent

Hi:

Has anyone had ideas about how to calculate the instability flow by using Fluent? I have calculated the flow field, I wonder how to make judgement if the flow is stable or not, or if there is a way to calculate the instability by fluent.

Thanks

Some turbulence models are better at predicting sensitivity to the real flow instabilities. Among the two-equation models, the best choice would be probably the RNG model. (See Fluent User's Guide 10.2.12)
