This seems to be the classic setup for finding singularities! So far:

• critical time for vorticity blow-up should be around t=5.2
• initial setup: done (replaced periodic boundaries with larger box...)
• test runs:
  • 6.6M particles ([-2pi,4pi]³, h=0.1), 1024 cores, no remeshing: vorticity blow-up after t=4.8
  • 6.6M particles ([-2pi,4pi]³, h=0.1) initially, 1024 cores, remeshing every 5th step: tba
  • 53.1M particles ([-2pi,4pi]³, h=0.05), 1024 cores, no remeshing: tba
