Ablative RT Problem

Docs from LLE

1. ​doc from Riccardo Betti;
2. ​equilibrium profile;

Implementation in the code

• Important Equations and Parameters: connect between Betti's parameters (temperature in Joule and everything else in SI-unit and the AstroBEAR code (everything in computational units).
  1. ​old way based on temperature equation;
  2. ​hybrid way: to get rid of the so-called gamma7 term in the diffusion solver;
  3. ​new ways solving energy equation;

• Stencils for diffusion solver: [ThermalConduction]
• Transfer the initial data to coarse grid with AstroBEAR and so it can take advantage of AMR: bliu08282014
