Hi @gcanfield,
I also think it is the best way to calculate the forces of car from the coefficients.
These coefficients are distributed to the front Cl(f) and rear Cl(r), not to each wheels.
I calculated the coefficeints in the setting as in the figure below.
I do not have conclusive evidence of the setting because it was judged only by myself, but I was determined that they are probable from the following points.
- The coefficients calculated in Result Control matched the coefficients calculated manually using forces in Result Control.
- Manual calculation formula was the same as the one that is written in the code. OpenFOAM-2.1.x/src/postProcessing/functionObjects/forces/forceCoeffs/forceCoeffs.C at master · OpenFOAM/OpenFOAM-2.1.x · GitHub
- When I removed the rear wing that is almost above the rear axle, the reduction of Cl and that of Cl(r) was almost the same without change of Cl(f).
Trials and errors of these settings remain in the following simulations.
- fp-023b Test-C https://www.simscale.com/workbench/?pid=4105619712994739995#tab_1-0
- Simulation 1 2 → Run 7 to 11
- Simulation 1 2 2 - No Rr Wing
I would like someone to confirm wheather the setting is correct or not.
Anyway, I hope this post helps @gcanfield.
Best,
Yosuke Yamamoto
