Can't merge the solutions
 
When I ran incomp_euler/channel in parallel, the following error occurred after Exit Success (SU2_CFD). It seems that it can't merge the 1000 solution files (.su2).
Code:

------------------------- Exit Success (SU2_CFD) ------------------------

Traceback (most recent call last):
  File "/home/SU2/bin/parallel_computation.py", line 111, in <module>
    main()
  File "/home/SU2/bin/parallel_computation.py", line 56, in main
    options.divide_grid  )
  File "/home/SU2/bin/parallel_computation.py", line 97, in parallel_computation
    info = SU2.run.merge(config)
  File "/home/SU2/bin/SU2/run/merge.py", line 64, in merge
    special_cases = su2io.get_specialCases(konfig)
  File "/home/SU2/bin/SU2/io/tools.py", line 702, in get_specialCases
    raise Exception(error_str) 
Exception: Currently cannot support FREE_SURFACE and UNSTEADY_SIMULATION at once

Please help me with this. I'm quite confused. Thanks in advance!

hi, could you please provide your config file? it seams that you are trying to run a freesurface simulation and unsteady simulation at the same time?

Hi,

I have the same problem (same errors in the python skripts) when I try to run SU2_SOL on a Cluster (parallel).

------------------------- Exit Success (SU2_CFD) ------------------------

the command: mpirun -np 12 /home/staff/kocj/unix/SU2/build.gcc/bin/SU2_SOL config_SOL.cfg
the location: /home/staff/kocj/unix/SU2/EULER3.1
Traceback (most recent call last):

raise Exception , message
Exception: Path = /home/staff/kocj/unix/SU2/EULER3.1/,

I have no problem on SU2 3.0 and 3.1 if I run (parallel) the simulation on my local machine.

Anyone has a Solution?

Ciao

Thank you for your question.
Since the problem occurs on one machine and not another, I would recommend first double-checking the installation on the cluster. It looks like this is an error that is unrelated to the previous post. If you are able to run in serial on your cluster, the problem is likely with the compilation settings for parallel, for example making sure that METIS and MPI are linked up to SU2 in the compilation.
