Description
The attached grid crashes with c10_branch@4322 and newmole@4322. The situation is better with c10_branch since there only 4 grid points crash:
IONIZATION PARAMETER= -1.000000 LOG METALS= 3.250000 LOG GRAINS IONIZATION PARAMETER= -0.500000 LOG METALS= 2.750000 LOG GRAINS IONIZATION PARAMETER= -0.500000 LOG METALS= 3.750000 LOG GRAINS IONIZATION PARAMETER= 0.000000 LOG METALS= 3.750000 LOG GRAINS
On newmole the following 8 grid points crash:
IONIZATION PARAMETER= -1.000000 LOG METALS= 3.250000 LOG GRAINS IONIZATION PARAMETER= -1.000000 LOG METALS= 3.750000 LOG GRAINS IONIZATION PARAMETER= -0.500000 LOG METALS= 2.750000 LOG GRAINS IONIZATION PARAMETER= -0.500000 LOG METALS= 3.250000 LOG GRAINS IONIZATION PARAMETER= -0.500000 LOG METALS= 3.750000 LOG GRAINS IONIZATION PARAMETER= 0.000000 LOG METALS= 2.250000 LOG GRAINS IONIZATION PARAMETER= 0.000000 LOG METALS= 3.250000 LOG GRAINS IONIZATION PARAMETER= 0.000000 LOG METALS= 3.750000 LOG GRAINS
In all cases the aborts were due to non-conservation of nuclei or densities exceeding MAX_DENSITY. The code was compiled with g++ 4.4.3 and MPI enabled.

This now finishes at r6340, albeit with a number of "PROBLEM CoolNet? derivative oscillating in initial solution" and "PROBLEM qheat did not converge grain" issues. One example of the latter is the U = -1, Metals = 2.75 point. With lgDoInitConv flipped to false in ConvInitSolution?, the former problem goes away and only the qheat issues remain. Changing component to grains, priority to minor, and type to "defect - convergence".
