Classes and Bugfixing 3

Astronomical Techniques

This week has mostly been a discussion of various statistics for finding distribution centers and spreads.

Numerical MHD

Finished debugging the HLLD solver. I didn’t find any bugs to explain the current issues so I moved on to the VL+CT integrator and found a sign error in the conservative update for the magnetic field in the $y$ direction. That changed the output but there are still significant errors that are likely in the velocity/momentum calculations and maybe in the boundary conditions. The current results of the Brio & Wu shocktube are below,
