Present: Roland, Ian, Peter, Steve, Yosef, Philipp, TwoPunctures: * fix is accepted. impact is unclear, should only affect convergence speed * Yosef suspects that this affects the direction that the solver takes since it only affects the preconditioner
McLachlan rewrite branch: * latest news: Erik wanted to run benchmarks, Ian will also try but is very busy, same for Peter MHD constrained transport: * Philipp, and the Caltech group have started discussion of constrained transport algorithms but have not reached a decision what to do * current best practice is to add some resistivity to the computation of the electric field, this is consistent with constrained transport. The numerical coefficient is 1e-3 -- 1e-4 . Currently this is under heavy development and not even in Zelmani yet. TOVSolver tying to GRHydro: * Roland will go ahead and remove the linkage Hydro in Kranc: * Ian Hawke (Southampton) is interested in doing a full timestep evolution scheme (some predictor/corrector) in Kranc Yours, Roland
