Disk runs

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

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 M_j 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: ~9.73M_j 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.

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.
