Default Using parallel computation

I am trying to run my case in parallel. I am using command 'parallel_computation.py -f XXXX.cfg -n NP' to run the case.
When I am running the case I can see a new config_CFD.cfg file being developed which looks like a copy of my own config file just removing comments. Can anyone please explain the importance and use of this file?


Also, ideally flow.vtu etc. files should get generated only after the end of simulation(after convergence) as mentioned in the forum before but even when I am terminating the simulation in between I can see the generated flow.vtu, surface_flow.vtu files. What can be the reason to it?


P.S- I am new to SU2


.cfg file can be seen here for reference

Hi Shahidkhan,

The python scripts will generate a config file for each binary they use.
For example: A config_CFD, config_DEF, config_DOT can be generated when using the discrete_adjoint.py. The XXXX.cfg and config_CFD.cfg should be functionally the same. Its an effort to not overwrite your original file.

SU2 will generate intermediate flow.vtu and surface_flow.vtu depending on the "OUTPUT_WRT_FREQ" option.

Let me know if this helps.

Ya this really helps. I am new so I am posting my doubts to learn more about the software.
