compute new ntogo in tick.f rather than incrementing by 1 #580

Closed rjleveque closed 6 months ago

rjleveque commented 6 months ago

In some tests this leads to fewer ntogo errors (too many dt reductions) than the old way, but doesn't entirely fix the problem.

This PR also contains some other modifications to tick.f:

Output frames rather than a checkpoint file if it dies with too many dt reductions (cannot properly checkpoint since not at end of coarse timestep)
Some debug statements that can be turned on
Properly compute timenew
Look for file STOP rather than STOP.txt to signal user wants to stop and checkpoint ASAP.
