i install a parallel version of SU2,and instal numpy,scipy,mpich2 and python 2.6.but when i enter "parallel_computation.py -f turb_ONERAM6.cfg -p 2",an error ocurred(as the attached picture).can anyone help me?

It seems that the python does no recognize the os module... you can google "No module named os"... it seems that your python installation is not ok.

But you can always run SU2 directly.
>mpirun -n 2 SU2_DDC turb_ONERAM6.cfg
to divide the grid and then
>mpirun -n 2 SU2_CFD turb_ONERAM6.cfg
to run the code in parallel.

Best,

thk for your reply,and i finally get the python environment done,and now i can run a case in parallel mode.but i get an error of SU2_DDC.exe,as the pic follows :

though there is an error,it can run, i just wonder does it matter to get a right result ?
ps:
i did "mpirun -n 2 SU2_DDC xx.cfg",but it returned an error like"unknown option -n"

best regards!

I do not know what platform you are on, but the mpirun syntax is:

mpirun -np nn where nn is the number of processes.

eg. mpirun -np 24 ./example input.cfg

Note it is -np not -n.

SU2 is not supported for parallel on windows at the moment. You should be able to run it serially though

My friend from NUAA.

I think the SU2 on windows is not perfect for parallel computation.

I think you should switch to Linux .
