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

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
Effect also visible on mass plot:
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.
