MHD Piecewise Parabolic Reconstruction (PPMC) This week I refactored PPMC and added MHD support to it. It was mostly using functions I wrote for PLMC with a couple small additions. Despite this si...

MHD Piecewise Linear Reconstruction PLMC is done and in PR #288. I ran into some issues with the verification of the blast wave and Orszag-Tang vortex but both turned out to be initial condition i...

MHD Piecewise Linear Reconstruction PLMC is pretty much done. I spent the week debugging it and making some other tweaks. There’s some cleaning up to do and final verification but that should be d...

MHD Piecewise Linear Reconstruction This week I started on the MHD piecewise linear reconstruction in the characteristic variables (PLMC). The steps I’ve completed are as follows: Do some rese...

MHD Advecting Field Loop This is done and in PR #273. Last week I discovered that the issues I was having with it were just due to some errors in how I was computing the mean magnetic pressure du...

Angled Linear Waves After a lot more work this week I discovered that my implementation of linear waves from the vector potential did not in fact pass with grid aligned or angled waves. Since this...

Circularly Polarized Alfvên Wave Test (CPAW) I finished the CPAW test. There were a few other bugs in the initial conditions but I got those sorted and cleaned up the code, wrote the tests, and su...

Circularly Polarized Alfvên Wave Test (CPAW) I worked this week to add the CPAW initial conditions and test based on the CPAW test in Gardiner & Stone 2008 and the Athena++ source code. The im...

MHD Debugging I’m pretty sure that MHD is finally debugged! I found a couple of bugs and typos in initial conditions in the shock tubes. There were typos in the papers I was referencing, the fixed...

MHD Debugging I found the issue I was struggling with last week with some help from Alwin Mao. It turns out that since MHD is face centered it needs the ghost cell closest to the grid to always ha...
