When a run is restarted, will Athena++ reread the input file and account for any changes there? Is it possible to compile a different configuration and then restart?
Specifically, do any of the initial mesh routines get rerun at the start of restart e.g. InitUserMeshData? Or is the purpose of restart files more to protect against crashes rather than allow for implementing changes at checkpoints?
(I raise this as a potential tool for probing behaviour leading up to errors occuring, where I might change solver, reconstruciton or user routines to bypass the error without having to rerun the entire sim from start)
