Hi everyone!
I am currently working on Shape Optimization of automobiles using Adjoint solvers. I have been working with an OpenFOAM based solver called "adjointSensitivityFoam". However, I felt that SU2 has better libraries for this purpose and have started exploring the same. While I was trying to run the "steady_oneram6" testcase by following the tutorial here (https://github.com/su2code/SU2/wiki/...f-a-Fixed-Wing), specifically when i type "shape_optimization.py -f inv_ONERAM6_adv.cfg", I get the following error. ------------------------------------------------------------------------- | ___ _ _ ___ | | / __| | | |_ ) Release 5.0.0 "Raven" | | \__ \ |_| |/ / | | |___/\___//___| Aerodynamic Shape Optimization Script | | | ------------------------------------------------------------------------- | SU2 Original Developers: Dr. Francisco D.

Since I am new, I am finding it difficult to understand the root cause of this error. It would be great if anyone could help me out. Thanks in advance!

When running the shape optimization simulations, individual log files are stored in the DESIGNS/... subdirectories. Do you seen any more information in these log files?
Based on the date of your post, you may also benefit from downloading the most recent version. Quote:
