Hi,

We had 12 people present: Phillip, Josh, Peter, Steven, Frank, Jonah, Erik, Barry, Zach, Matt, Ian, and Roland.

Besides mentioning a few "minor" tickets, the top discussions were:

- how to expand variables in parameter files (a question which now seems to be settled, more here: https://trac.einsteintoolkit.org/ticket/1651) - git move: should wait until Jenkins comes up again, at least if this isn't too far into the future (hopefully this week) - GRHydro/Illinois/Whisky inconsistency: reason still unknown. Zach has more puzzle pieces, but they also pose more questions. It seems that we don't have an edge or even corner yet, and attention and interest is waining. What we know so far (please correct me if I am wrong): - The 2-norm of the Ham. constraint is about 2x high with GRHydro than both with Whisky and the Illinois code, plus there are differences in the drift of the central density (probably related). - This does happen with HLLE, but not Marquina - It does not happen in Cowling - Nobody could find a major difference in the HLLE code - The Illinois code uses another definition for the velocity - a possible source for this difference, but Whisky uses the same as GRHydro
