v18 v19 43 43 44 44 45 I see that Mbe crit is below the minima of M(t). This is no doubt due to some SMALL round-off error somewhere in computing the total masses in the grid. If for instance, I use simply the formula above to find the mass of the sphere, it does not. So instead of using that in my spreadsheet, I use the mass of the sphere as given by visit, I get:45 I see that Mbe crit is below the minima of M(t). This is no doubt due to some SMALL round-off error somewhere in computing the total masses in the grid. If for instance, I use simply the formula above to find the mass of the BE sphere, it does not give me exactly what my code gives. The Visit calculation gives me ~0.78 whereas my code says it is ~0.72 -- in line with the Crit Mbe as expected. 46 46 47 47 Now, it should also, be noted that the crit Mbe is computed by the formula: 48 49 50 {{{#!latex 51 M(t, 1.1Rbe) = Mtotal(t)-Mambient(t) 52 }}}. 53 54 This describes __ blah blah, whereas my sphere is _blah Blah. 55 56 57 I guess what can be taken home safely from this curve is that M(t) does not fluctuate wildly, and never goes more than 10% over the crit Mbe.
