Drag coefficient as a solver criterium
 

Hi,

I want to calculate drag and lift coefficient in a simulation, but don't know how despite searching this forum.

Since I have a complicated geometry - a car - acquiring the frontal area seems to be a problem in the function calculator (as suggested in other threads), so I assume this is not the way to go.

Besides that, there is another problem with using the function calculator. Since drag and lift are the results of my simulation, I want to make sure that they are converged, so I want to use them as criteria for the solver.

I hope you guys have any clue what to do since this seems impossible to solve by myself. And could you please write it in a way so even a noob like me understands what you're talking about...

Thank you very much in advance!

Has been a few weeks and as summer vacation is over now, I hope someone will be able to help me. Please, if you have any advice, let me know - I just can't solve this on my own! Thanks!!!
