SU2 7.0.7 Built on CentOS 7, parallel computation pyscript mpi exit error?

EternalSeekerX · October 9, 2020, 05:13

Hello everyone,

So I was testing SU2 parallel on my CentOS 7 machine. For this test I was running the Unsteady NACA 0012 compressible case. I ran it using 6 processor cores.

I notice that it satisfies convergence criteria at restart_flow_00532. And that is when the script launches the SU2_SOL and this is where the error shows up.

Code:

----------------------------- Solver Exit -------------------------------
All windowed time-averaged convergence criteria are fullfilled.

It seems that when the script reaches the last data file, it throws this error, is this expected? Seems like mpi doesn't like being closed like this?

Thanks

SU2_SOL is no longer necessary, files are written out by SU2_CFD using parallel I/O.

The parallel_computation script has lagged behind and still calls SU2_SOL (which used to be necessary in version 6).

Best advice I can give you is forget about all the "friendly" python scripts, just run mpirun/mpiexec -n ? SU2_CFD.

Ahh, I got it. I'll try using mpirun then. I did notice even with the script, It exits SU2_CFD fine and also even with the mpi error when running SU2_SOL all the result files do output and everything works fine, just mpi gets whirly about it. So I can safely assume my install was correct?

Edit: Just ran using mpirun and it completed the run and written the vtu files perfectly. So yeah I think the build went correctly then!?

Yep all should be fine.

At the moment SU2_SOL is only useful if after running SU2_CFD you want to export to a different format.
The problem you described sounds like a bug in SU2_SOL for time domain problems, we'll have a look.
