CFD++ Axisymmetric simulation problem.

Panglos · September 15, 2015, 10:01

Hello,

How can I calculate forces and coefficients for an axisymmetric simulation on CFD++ ?

I made an axisymmetric simulation on CFD++ of a little cubesat.
I found some problems with "CFD++ probe filter", since when I try to evaluate the forces acting on my vehicle or when I try to estimate the lift and drag coefficients I obtain strange values that don't correspond to the reality of the phenomena.

Thank you in advance

How do you want to calculate lift in a rotational system? If don't think that's possible.

Well, actually I only need for the drag coefficient.
