Present: Frank, Roland, Erik, Steve, Peter, Zach, Vassilli, Matt, Philipp, Ian
Run issues: Vassilli sees decrease in irreducible mass in his runs at at time after the initial junk should have passed. Increase is a bout 4-5%, suggest to check increasing resolution globally to verify if effect is physics or numerics. Examples: * Roland tried NsNs purely Cartesian run, sees NaN after about 50M, will test if NaN is also present in the original multipatch run of comparable resolution * Peter to dig up parfile and runtime/memory estimates for bbh runs IllinoisGRMHD: * Zach to give a code walkthrough next week in the ET call * will use BigBlueButton for this (http://horizon.tapir.caltech.edu for a test video), Roland will test that this works beforehand Ps4 mode decomposition: * Jim Healy sees some odd behaviour in 2,1 mode of psi4 when using Multipole thorn but not when using old GT mode decomposition thorn * mode that is expected to be zero is not and leads to BH kick * run uses rotatingsymmetry180 and reflectionsymmetry (in z direction) * no physics change in multipole since Oersted release * suggest running in full mode * will work with Jim for a while then possibly take issue to mailing list again Yours, Roland
