- | * E_blast = 10^49 erg (all placed within innermost cell) | + | * E_blast = 10^49 erg (all placed within innermost cell). Leads to a max temperature of 3 GK in zone 30/400. A full 10^51 erg explosion causes temperatures to exceed XNet's capabilities. This is because the 5/3 cold degenerate equation of state with mu=1/2 is crap in this regime. A star with radially varying composition, and an equation of state to reflect that, is required for additional realism. |

+ | ppmlr.f90 needs to be modified so that once the Lagrange step was taken, the values needed to not be put back onto the Eulerian grid. | ||
+ | * remove the "wiggle" part of the file that adds dissipation for carbuncular noise. Since this is only really a problem in higher dimension, we completely removed this for simplicity. | ||
+ | * Instead of defining xf=xf0 define xf0=xf (i.e. make the Eulerian coordinates move to match the Lagrangian ones) | ||
+ | * If the final "remap" command is commented out, the code misbehaves, though we don't know why a remap should be needed. Leave the final remap in. | ||
