Dust in AstroBEAR - Update 2019/12/09 and 2019/12/16

Objectives

  • Debug & test advection & sputtering routines
  • Continue implementation of grain-grain collisions

Progress:

  • Debugging: Still debugging, found one big bug and fix it last week so going well. Found an issue with the interpolation routines for the dust. Not quite sure yet what's happening here.
  • Grain Growth: I think the ion trapping routine is more or less bug-free now, working on feedback effects on the gas since we couldn't consider that for dust post-processing.
  • Grain-Grain Collisions: I'd say this is about 30% done now, aiming to finish by the new year
  • New Problem Setup: Finished tweaking that. A sample simulation can be found here: ​Video.

Issues & Questions:

  • Performance: Is there a way to find out how much time the code spends in certain routines?
