aero_opt.py killed during "Solving ADjoint Transpose with PETSc..."

[ardaozuzun]

During the aerodynamic optimization tutorial, I encountered issue #96 which I resolved by replacing the pyoptsparse version with 2.10.0. However, I am now facing a new problem while using docker u22-gcc-ompi-stable. Optimization cannot proceed the following step (Solving ADjoint Transpose with PETSc...) and it is kiiled. I have increased swap memory but it did not solve the issue.

I also encountered the same problem. Then I changed another PC with larger RAM and it can run again. Maybe you can try to run it on another higer performance PC.

I followed exactly what you did, and the issue was resolved. However, it's interesting that increasing swap memory didn't make it work.
