Hello everyone,
i am new with SU2 and trying to do tutorials. But i can't do the parallel computation with PBS.
i got an error when i wanted to submit PBS file using qsub command.Interior of the PBS file is as follows:

#!/bin/bash

# Specify time limit of your job. (HH:MM:SS)
#PBS -l walltime=02:00:00
# Specify the number of CPU cores/parallel processes you need
#PBS -l procs=4

# mail alert at the (e)nd of execution
#PBS -m e
#PBS -M mail@ae.metu.edu.tr
# Give your job a name so it can be found readily with qstat.
#PBS -N name

# standard error output merge to the standard output file.
#PBS -j oe
# Specify the file name for the standard output/error
#PBS -o output
#PBS -e error

# Enter your work directory under /cfd
cd working_directory

# Execute your parallel program
/opt/SU2/bin/parallel_computation.py -f inv_ONERAM6_JST.cfg -n 4

And the error is:

Traceback (most recent call last):
File "/opt/SU2/bin/parallel_computation.py", line 26, in <module>
import SU2
File "/opt/SU2/bin/SU2/__init__.py", line 3, in <module>

from lhc_unif import lhc_unif
File "/opt/SU2/bin/SU2/util/lhc_unif.py", line 1, in <module>
import numpy as np
ImportError: No module named numpy

On the other hand when i run the python script on command line as follows:

/opt/SU2/bin/parallel_computation.py -f inv_ONERAM6_JST.cfg -n 4

it works and creates all of results correctly.

i added paths SU2_RUN and SU2_HOME to my .bashrc
i don't know how to apply the python script (parallel_computation.py) in PBS.
Any help will be greatly appreciated.

Thanks in advance

You should install some soft to make python run in parallel computation. In my case, I don't use parallel_computation script to run. I use following script as the PBS task

#

thank you very much Liu

it seems it worked

If you want to SU2_SOL to post-process the solution, you should make sure the name of Restart flow input file is same with the name of Output file restart flow. You can try several times, then you can understand.
