Our initial results from subch_planar suggest that the behavior of the initial detonation in a ddet SN Ia is dependent on the composition gradient between WD and accretion layer. Here, I am setting up a 1D problem based on Detonation. The goal is to interpolate from a set envelope composition on the left to a set core composition on the right, representing the 2D gradient.

This is starting to look better

This now has the transition region about the center of the domain, with a transition width given by problem.delta

…temperature change with species composition.

This now creates a new parameter, T_ign, that represents the initial hotspot temperature. I have separated this from the accretion envelope temperature to better represent the initial He detonation. Additionally, T_l now falls to T_r in the same fashion as the species composition.
