sphereDrop tutorial does not run to the end
Summary
sphereDrop tutorial does not run far with layer addition.
Smaller issues:
- runs with PCG on pcorr but GAMG on p_rgh
- runs pcorr to unnecessary tight tolerance?
Steps to reproduce
Change end time on sphereDrop tutorial to 0.7 instead of 0.07.
What is the current bug behaviour?
Case diverges at some point - alpha max gets above 1.
What is the expected correct behavior?
Relevant logs and/or images
At around time 0.1992 the deltaT goes from e-5 to e-6 due to the Courant number. After that it starts getting lower and lower (assume velocity goes up - not checked). I've tried with 4 outer correctors but that didn't help.
