MHD Piecewise Parabolic Reconstruction (PPMC) I’m still stuck on the oscillation in the Brio & Wu shock tube. It seems like it might be an issue with the method/limiters not working for MHD ra...

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...
