Co-rotating binaries disk formation sims No .1

6 June '12, 10 AU case, Mdotprimary=10-5Mo yr-1

http://www.pas.rochester.edu/~martinhe/2011/binary/6jun12.png Disk mass evolution. Compare with pk model 2, fig. 1 top, but note that qpk=3 while qus=1.5. I'll soon have a similar plot for the 20 AU case which should be compared with M&M figure 5 bottom; M&M see an increasing disk mass with a final value of 5x10-6 Mo yr-1.
http://www.pas.rochester.edu/~martinhe/2011/binary/7jun12.png Evolution of the mass accretion rate onto the particle. The converging value of ~5x10-6 seems a factor of 50 higher than expected. Comparing with table 3 M&M, models 1 and 2: MdotM&M~.9-3x10-6 ; Mdotus~5x10-6, so we seem to be off for a factor of order 1.6-5.6. Comparing with pk model 2, fig. 1 bottom, (but note that qpk=3 while qus=1.5) we are off by a factor of ~30. Investigating further.

-20au preliminary early evo test with more resolution than before, http://www.pas.rochester.edu/~martinhe/2011/binary/20au-1000k-64x64x32-4amr-correctWINDdens.gif. This sim has a resolution of 64x64x32+3amr. AGB wind inflow enters the -x, +y and +-z boundaries. Improved versions of this sim are running in ranger and queued in kraken.

a No. density log grey scale [cu] + color velocity [Mach]. Top left, top right, bottom left and bottom right show the entire orbital plane, a zoom into the orbital plane, the entire longitudinal plane for a phi angle parallel to the wind at the origin, and a zoom into the longitudinal plane, respectively.
