Default Output data sets for each monitored surface

Hi all,

I am struggling to discover how to have SU2 output separate data sets for multiple surfaces. For example, I have a cylinder in cross flow. Attached to that cylinder is a flat plate that is aligned so as to be roughly tangent to the surface of the cylinder. In the end, I would like to have 3 data sets: (1) the pressure distribution over the whole system, including cylinder and flap, (2) the pressure distribution on both sides of the flat plate, and (3) the pressure distribution over the cylinder. Another way of looking at it is: I want to find the contributions to lift from the cylinder and plate separately.

I am currently specifying the cylinder surface and the plate surface in the "marker_monitoring" parameter in the configuration file. That gives me total lift, which is only part of what I'm looking for.

Thanks for the help!

Thanks for your question. Unfortunately this capability is not currently available.
What you can do is to repeatedly run SU2_SOL, which will post-process the solution data and produce the surface plots without re-running the simulation. You would just need to change the value in MARKER_PLOTTING each time, and you make sure that you have the right restart file under the right name (usually restart_flow.dat - if SU2_SOL cannot find the file it is expecting, it will print an error saying what the file name ought to be). This will overwrite suface_flow.dat each time, unless you change SURFACE_FLOW_FILENAME in the config file.
