Update 7/13
Exo3
Posters. Mine is supposed to be MHD, though it can still be edited. I think we may have gotten enough to make an interesting poster, though, especially with the last frame or two of the most recent run. Current plan is to discuss Eric's theory about the field guiding the wind in a more LOS direction in the context of original parameter space run and new results.
MHD tests
Truly uniform, constant magnetic fields. Initial conditions are the same in each pair of strong/weak field runs, barring the magnetic field strength. All simulations are using outflow-only boundary conditions.
Haven't run the simulations including a stellar wind yet, a little more difficult to double check the implementation of those.

Charge Exchange
Solar-type wind crashed with MPI issues before completing a single frame. I've halved the number of cores to reduce the messaging, which should fix that.
Completed 3 (of 5 planned) frames of strong wind with collisional ionization:
