Hi, everyone.
I am currently working on outputting distinct variables for different surfaces in my simulation. I attempted to achieve this by setting "MARKER_PLOTTING = (surface1, surface2)," but encountered an issue where the surface.scv file combined information from both surfaces. This has posed challenges in subsequent post-processing.

I believe there may be a method to output these variables into separate files, but I am not yet familiar with it. I would greatly appreciate any guidance or assistance you could provide on this matter.

Thank you in advance for your time and support.

Best regards,

Zhang

Hello Zhang,

I have typically done the following for the scenario you describe:

1. Change MARKER_PLOTTING = (*just the required individual surface*)
2. Make sure SOLUTION_FILENAME is set to the correct restart file containing the data that's been computed.
3. Run SU2_SOL *file_that_contains_the_above.cfg*, then rename the surface output filename to whichever surface was just written (so it doesn't get overwritten when you repeat with the other surfaces...or you could rename what the surface filename is written as from the config, whatever is easier for your workflow).
4. Then repeat steps 1 - 3 but with the second (or however many other) individual surfaces.

While it doesn't write all of the surfaces as separate surface solutions into a single file (like Fluent or OpenFOAM or something), I have just been loading the separate written individual surface solutions into a single scene/layout to combine them in postprocess whether Tecplot or Paraview.

Hopefully this might help!

Thank you, Roy. Your advice help me a lot, I will try it again! Best wishes!
