Dust in AstroBEAR - Update 2020/10/19

Very short update this week:

Objectives

  • Debugging

Progress:

Gas Drag: I check the error sources I had identified and fixed some bugs (mainly typos with some constants) and both Spitzer1941 and Fry2020 grain charges now produce realistic charges. The simulations do look different but I'm very convinced now that there's something wrong still (​weird finger-like structures)

Sputtering and Grain-Grain Collisions: Got some benchmarking simulations set up for comparison to check whether the rates of destruction are reasonable or not.

Next steps:

  • Continue debugging hopefully shifting focus to sputtering soon
