Hello there, I tried to add this to another simpleFoam case. Interestingly my forceCoeffs are Cm = -9.13425e-10 Cd = 0.00573774 Cl = -7.90766e-07 Cl(f) = -3.96296e-07 Cl(r) = -3.9447e-07 But there's no CmPitch, CmYaw ...etc. what am I missing? Thanks for this great tutorial series btw!!
Thanks for your appreciation. The object is symmetrical about the horizontal axis. The lift force from the top would balance the lift force from the bottom. Hence it would be net 0. It is 2D. So we can't really expect Cm here. If other parameters are missing, maybe you are using OpenFOAM .org version and not ESI version. I hope this helps.
Hey! i really liked the tutorial but you mentioned sharing the file for turbulent steady flow. also i am working on validating the Cl and Cd for naca2412 but my results are aligning to the real data. if you could help with that thanku
The results depend on a lot of factors such as your mesh, the Y+, the relaxation factors, etc.. And sorry, I do not have the files I used for that simulation now.
thanks ❤
Welcome. ☺️🤗
please share the complete case, thx

@@Codeynamics do you have any case where you calculated Cl and Cd using simpleFoam
Regardless of the solver, the procedure is the same.
