I want to make su2 to only print the history file and restart file, I do not want it to write the solution file. Also if i call SU2 multiple times, is there a way for me to make it append my already exiting history.csv file rather than make a new one everytime?

Hi Tobi,

You can simply not print any other output files. That should solve the issue. And regarding appending the history file on calling SU2 multiple times, that is something that SU2 already does from what I understand. It just overwrites the same file if the file name remains the same.

Hope this solves your issue.

Hey, thanks for the quick reply, but how do i not print any output files. and also what im doing is that im conducting the simulation several times from another python program using the restart files. But everytime i restart the simulation a new history file is created. Is there any way i can append the first file that was created?

Hi Tobi,


a) We use restart-file and solution-file for the same thing. The former is written by a simulation and the latter is read for restarts. But they are the same file so-to-say. I guess you dont want to write a visualization file for Paraview/Tecplot. In that case set OUTPUT_FILES= RESTART (OUTPUT_FILES= RESTART, PARAVIEW_MULTIBLOCK e.g. would write output for visualization). For more info please look here https://su2code.github.io/docs_v7/Custom-Output/


b) Unfortunately I think there is currently no way to append to a history file. It also always starts to count from iteration number 1 each time.


hope that helps, Tobi (as well)

You can write a shell script like what I attached to do this.


If you set OUTPUT_WRT_FREQ= 10000000 (large number) it will write only when convergence criteria is met but then you can remove them at each of your runs.


Also I think you can do the similar thing with FADO. For that you need to put up a python script. Refer to FADO on github.


You can find the mesh on SU2's testcases:
