I have to run a CFD simulation of a diffuser that will be used in a Formula student car.
However, I was advised to begin with using k-omega or k-epislon models and then use LES model for more precision.
I always seem to be getting errors with I use k-omega in steady state (I am required to use k-omega in transient as well!).
My next question would be - how do I go about setting my simulation for transient models?
Any advice or help would be great.
