Dear Authors,
First of all, I sincerely appreciate your great work on DrivAerNet++ and for opening the dataset and related resources to the academic community.
I am currently trying to reproduce your external flow CFD simulation for vehicle aerodynamics.
However, I have run into two critical problems：
The drag coefficient Cd fails to converge and keeps fluctuating during iteration.
The calculated Cd value is obviously much larger than the official standard value given in the dataset.but I cannot find where the problem is.
I have attached my complete simulation setup files (all OpenFOAM dictionary files)，as well as the iteration curve of Cd and residual convergence curve for your inspection and reference.I would be very grateful if you could kindly give me some guidance.
I totally understand that you are very busy with your research work. Even a brief suggestion or key parameter reminder will be of great help to my study.
Thank you again for your generous open-source contribution and your kind help in advance.
