Classes and Bugfixing 6

Astronomical Techniques

More discussion of error propagation. Started planning class projects and discussed hypothesis testing.

Numerical MHD

Still working on bug hunting. I tested a bunch of different things and finally found the bug that was causing the \( B_x \) field to update. There was a copy/paste error in the CT field calculations and I was using the wrong velocity for one of the upwinding steps. My next step is going to be trying out simple waves. I’ll be using the wave tests from ATHENA++ which are detailed in Gardiner & Stone 2005. The discussion of linear waves has been moved to MHD Test Problems
