Dear Community,


I have managed to build and compile the source code enabling:
  1. autodiff
  2. directdiff
  3. pywrapper
as well as the default ones. During the meson build there were no warnings. Additionally, the environment variables were set as required on the installation page.


When I try to run the design features tutorial 1(https://su2code.github.io/tutorials/...ined_NACA0012/ ) apart from the fact that I have to manually specify the location of shape_optimization.py, the code does not work.



Running
Code:
$ python3 $SU2_RUN/shape_optimization.py -g CONTINUOUS_ADJOINT -o SLSQP -f inv_NACA0012_basic.cfg
in the corresponding tutorial folder the output I get is shown below:

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes. You may or may not see output from other processes, depending on exactly when Open MPI kills them. --------------------------------------------------------------------------
I would deeply appreciate any form of help and advise and I apologize if this is considered a rookie error but I have no experience on both SU2 and Linux as well. Thank you in advance.
