Error in running shape_optimization in parallel
 

Hello，everyone！
I have some problems in running shape_optimization in parallel.I running SU2 on Ubuntu.
When I enter "python shape_optimization.py -f pitching_ONERAM6.cfg",it runs all right.But when I enter "python shape_optimization.py -f pitching_ONERAM6.cfg -n 4",it shows an error like below,

Can someone help me？

best wishes！:)

It seems that it doesn't decompose the mesh.

Does the command below work for you?

mpirun -n 4 SU2_PRT pitching_ONERAM6.cfg

Thank you very much, Zen!
I have tried "mpirun -n 4 SU2_PRT pitching_ONERAM6.cfg" ahead and after the commond "python shape_optimization.py -f pitching_ONERAM6.cfg" , it showed the same error!
I also just run "mpirun -n 4 SU2_PRT pitching_ONERAM6.cfg", no new mesh was generated!

Is openmpi installed on your pc? did you get an error message if you run mpirun -n 4 SU2_PRT pitching_ONERAM6.cfg? or does it simply tun without partitioning the mesh?

Hi, Zen!
I have already installed mpich2.
if I run mpirun -n 4 SU2_PRT pitching_ONERAM6.cfg, it just read the grid without partitioning the mesh.

mmm, maybe you did not configure SU2 for parallel computations? Other than that, I wouldn't know where else to look.

Thank you very much!
I will try to install SU2 again!
