SU2_DDC ended prematurely
 
1 Attachment(s)
Hi all,
I am trying to run SU2 in parallel in Windows 7, so far I am not successful.
I installed HPC Pack 2012 R2 MS-MPI Redistributable Package and tested it with example. The example is executed without any problem.
After the test I tried to run SU2_DDC with out using parallel_computation.py, with the following command: mpiexec -n 2 SU2_DDC inv_ONERAM6.cfg
Then I got an error saying that SU2_DDC ended prematurely and may have crashed. exit code 0xc0000005
I have also attached the snap shot of the error. Any suggestion for this problem?
It would be great if someone could give me any advice on how to setup su2 parallel simulation in windows 7.
Thanks for the help.

I'm getting the same problem, further inspecting the issue it seems SU2_DDC is not able to correctly split the .su2 file and exists prematurely.

For example:

Running
Code:
parallel_computation -f config_template.cfg -p 2
(using mesh_NACA0012_inv.su2) results in two generated files (as expected) mesh_NACA0012_inv_1.su2 and mesh_NACA0012_inv_2.su2.
However, opening them reveals the following content:

mesh_NACA0012_inv_1.su2:
Code:
NDIME= 0
NELEM= 0
NPOIN= 0        0
NMARK= 0
NPERIODIC= 1
PERIODIC_INDEX= 0
0        0        0
0        0        0
0        0        0
FFD_NBOX= 0
FFD_NLEVEL= 11825
mesh_NACA0012_inv_2.su2:
Code:
NDIME= 26991
NELEM= 0
NPOIN= 0        0
NMARK= 0
NPERIODIC= 0
FFD_NBOX= 0
FFD_NLEVEL= 8236
I'm running the pre-compiled version of windows x64 bits on Windows 8.1 x64

:confused::confused:
