Hello,

I am carrying out a numerical simulation on Buffet phenomenon over a supercritical airfoil. now I have carried out the steady simulation and I yet couldn't figure out how to use the time step size(s) and I don't know how many number of time steps that I should use.

my Flow through time is 0.027s. so from where do I start the unsteady simulation?
and also is it alright to increase the courant number around 300 step by step?

I am expecting to get around 11 oscillations.
