Hi all,

I am modelling a flow over bluff body and using an unsteady k-e model. In the literature, I found that when using unsteady solver, the force monitors i.e. lift and drag force will fluctuate like a sine function and we can get the average or max of that. I did not get the fluctuation in drag and lift coeficients. All I got is the same as steady solver where the coefficients will converge at one particular value. Is there something wrong here? I hope someone can clarify.

Thanks, Sham.

Than may be your problem is not a unsteady one.
