Definitely no inflow at top or bottom - star appears to reach steady state, not sure why beginning is unstable.
Stellar Explosion
Looking four cells in doesn't seem to help with keeping the stellar Parker solution static. I'll dig around in the code a bit soon, but to start, here's what happens:
Comparisons + Mass over time
White contour is the boundary of the star. The scale height of the disk (c/omega - for units of meters) is much smaller than the resolution - it's about 4 millionths of a computational unit.
Just for comparison are weighted sum of density for whole box over time, weighted sum for cylinder, and weighted sum for prism:
Y-axis is in computational units; multiply by 1.29236x1020 for units of g.
3x3x1
Looks like the boundaries are still too close - increase half a CU on either side in x and y and 1 CU in z (for the strange wave pattern - is this a problem?)? Reluctant to increase the dimensions too much more - these simulations are only 2 levels of AMR, and already take ~3 days to run - but I could run a much larger simulation for a long time once, just to see the extent that we do need to get.
