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...

Automated Testing I spent about half of this week getting automated testing working with Jenkins. I had some issues with clang-tidy’s header filtering not working properly but after that it was mo...

Clang Tools The clang tools PR (PR #211) has been merged! At the beginning of this week I rebased it for the other PRs that have been added and I wrote a script to help summarize the output of cla...

MHD Refactor This week has mostly been addressing issues raised in the code review of my MHD PR. Mostly that was moving some functions out of Grid3D and into the MHD namespace, adding comments, ci...

Clang Tools I made some tweaks to the clang tools PR (#211) to get it ready. I removed the clang-tidy run on ROCm since it’s not working. If we figure out how to get it working I’ll add it back. I...
