I ran the Caradonna and Tung rotor test case included with the source code using the command

mpiexec -np 16 SU2_CFD rot_caradonna_tung.cfg

, which completed successfully. Then I tried to post-process the restart file using

SU2_SOL rot_caradonna_tung.cfg

First, this gave me the following error:

Unable to open SU2 restart file solution_flow.dat

I managed to get around this by changing line 209 of the .cfg file to point to the restart_flow.dat file instead of solution_flow.dat like this:

SOLUTION_FLOW_FILENAME= restart_flow.dat

Is that what I am supposed to do?

Regardless, after the changes the SU2_SOL command ran successfully and generated the desired surface_flow.vtk Paraview file for me. However, it seems something went wrong, because this is what the rotor geometry looks like when I opened the file in Paraview:

Any help figuring this out would be greatly appreciated.

It turned out that I was trying to post-process the solution using the sequential version of SU2_SOL, whereas I should have used the parallel version instead, because I ran SU2_CFD in parallel too.
