Present were: Roland, Frank, Philipp, Peter, Erik, Christian, Josh, Bruno
ET summer workshop: * want to offer new users workshop again * want to attach it to existing conference/workshop * Christian is hosting a summer school on astrophysics at Caltech in summer. - try to attach to this - school ends on Saturday, ET workshop Mo-Tue - apply for support for students - wait for logistics to be sorted out at Caltech (exact dates, rooms)
MHD: * Bondi test now works for 5M, 900 iterations using smoothing initial data * characteristic speeds: Bruno is working on them, worked on it during the weekend * compared to constraint transport Philipp found more noise in refinement boundaries when using divergence cleaning * suggestion to use carpet::use_overlap_zones = yes which might help (Philipp will also try the TOV star with this) * refluxing: Roland looked at his commit and does not understand why this should ever have worked. Tried refluxing with a magnetic field and found that it does not conserver sum(Bcon). Refluxing with constraint transport is broken since capturing the fluxes has to be done differently for constraint transport * Philipp has manged to fix his c2p failures * Bruno will try CarpetEvolutionMask to see if this helps avoid aborts du to spurious NaN values
Yours, Roland
