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 roundoff 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 roundoff 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.
