Disk runs

  • Temperature = 104 K
  • Max mach = ~55
  • Soft_radius = ¼ rDisk

Orbit time

r = 2*1010cm
v = sqrt((1.89*1033*6.67*10-8)/(r)) = 7.93*107 cm/s
t = (2*Pi*r)/v =~ 1500 seconds

AMR 4

AMR 5

  • 10 Jupiter Mass disk (Time 0-1)link
  • 10 Jupiter Mass disk (Time 1-2)link

Disk Mass accuracy

Thickness = 0.1d0 With a value for thickness option set to 0.1d, disk density is smoothed at boundary with ambient (r>3.9d0).

Thickness = 0.0d0 Obvious increase in mass.

Not 10 Mj mass accountable from radius not being exactly 2e10cm and height not being 4e9cm.

  • Actual radius = 3.984376*lScale=3.984376*5e9=~1.99e10
  • Actual height = 0.781248*lScale=0.781248*5e9=~3.90e9
  • Estimated density for a perfect disk = 3.7754 g/cc

Expected mass given the 3 quantities above: ~9.73Mj which is pretty similar to what we observed.
Verdict: Mass readings are accurate, should change density to adapt to not exact disk dimensions, decision on thickness.

AMR bleeding

Collapse

These stills show how the pressure profile collapses in a very short time when the sim starts.

Interesting Patterns

A spinning spiral pattern that was present in some of the movies is now visible in detail with this increased AMR level.
