SU2 parallel optimization problem

n.d.ageev@gmail.com · January 31, 2019, 12:28

Hello everybody!
I am trying to perform simple tutorial on optimization (inv_naca0012_basic.cfg) on Windows machine with precompiled binaries (v. 6.0.0). In serial mode it works well, but in parallel i've got some problems. The optimization starts, but only restart_flow.dat file is generated. It looks like SU2 _SOL.exe don't work (I don't know why, if I run it from DSN directory for config_SOL.cfd everything is OK). Where I can find the place in the script where SU2_SOL.exe is called?

With version 5.0.0 everything is good with the optimization.

Best regards

I solved this issue by replacing line 237 in the /SU2/SU2/run/interface.py from "the_Command = 'SU2_SOL ' + tempname" to "the_Command='SU2_SOL%s
%s' % (quote, tempname)"

I will be glad if somebody helps me to post this on github.

Update: the same thing with SU2_GEO.

Hi,
In paralel mode, in order to decrease solution time program does not write flow.dat file. You can write solution file by using su2_sol.exe manually.

I know. But for optimization as I understand the flow.dat is necessary.

Oh sorry, i do not notice optimization. I have similar problem with you. After i solved a problem with 3000 iteration in parallel mode, program gives an error when i try to continue solution with restart file. If you find a solution, can you share with ne?
