If I use the python library to call SU2 and run in parallel, the simulation runs to completion but then repeats the simulation x-number of times, where I think x is equal to the number of processors. Also the run times reported are for the number of processors specified. The issue can be repeated with the following python script:



config = SU2.io.Config(filename)
config.NUMBER_PART = 4 # 0 for serial
config.NZONES = 1
SU2.run.CFD(config)


However, the simulation works in parallel as expected if I use the terminal commands:


mpirun -n 4 SU2_CFD filename.cfg


Any ideas?


*UPDATE1*: issue partly resolved, the parallel_computation.py scipt in the SU2_PY directory ran the simulation in parallel without repeating. Still not sure why the above python script does not work, however.
*UPDATE2*: issue fully resolved, I was calling SU2.eval.func('DRAG', config), SU2.eval.func('LIFT', config), and SU2.eval.func('MOMENT', config) in addition to SU2.run.CFD(config)
