Restart file format for unsteady rotating frame simulations

[koodlyakshay]

Hello,

I am running an unsteady rotating frame simulation with the flow solver. When I try to restart simulations, I get the error restart_flow_00<iter>.csv file not found. I was surprised why the .csv file is needed here.

Tracking the origin of the error in the code, I see it is coming from the routine Restart_OldGeometry which is apparently only called in the condition dual_time && grid_movement && (not) deform_mesh && (not) rigid motion in the routine LoadRestart_impl. The Restart_OldGeometry (in CSolver.cpp) routine forcibly appends the .csv to the filename.

Is there some workaround for this? Is there a config option to write a csv file when running the simulations? I prefer to use the binary restarts since the mesh is quite large and I don't want to have too many very large restart files.

Thanks in advance.
