I intend to calculate lift and drag coefficient over a rotating cylinder in k-epsilon model (2D). But i am facing trouble to compute lift and drag force.
Is there any function to calculate lift and drag force in turbulent flow such as reacf(x) in laminar flow ?

Dear Shoaib,

my colleague wrote a blog on this subject:

This should explain all the steps that you need.

Best regards,
