python wrapper of AVL's fortran layer made using f2py
I am an aerospace engineering with experience in aircraft design and scientific computing. My research has focused on gradient-based shape optimization using computational fluid dynamics (CFD) in addition to the developement of CFD solvers. I am also interested in nonlinear and linear solvers, high-performance computing, and next-generation aircraft design
For more information and preprints of my research papers see my website or ResearchGate

Hello @joanibal ,
I'm trying to run the run_opt example without success - CL and CM constraints are not matched.
I have installed openmdao 3.30.0 and pyoptsparse 2.20.2 on Ubuntu 20.04.
Find attached my example folder with additional outputs/reports.
OpenMdao is new to me, so I have no clue what's going wrong and it would be very nice if
you can give some help.
Thanks in advance.
John
Hello @joanibal could you please advise what the license is for this package?
Thanks in advance
Hey Josh,
writing the optimized geometry with "...avlsolver.solver.avl.write_geom_file(OptGeoFile)" has no body data included (if
available).
Cheers,
John

Based on this stack overflow post this issue is related to translating 64 bit memory address to 32 bit addresses.
The linker relocates data in the .o based on its new memory address in the linked program.
A similar operation (R_X86_64_PC32) occurs in the linux .o files so the operation itself may not be the issue.
I tried..
