Present: Erik, Roland, Steve, Jay, Liwei, Lorenzo, Lucas, Sam updates: * no updates from Roland * Lucas is proceeding with documentation, is now in mostly good shape * Liwei still working on fixing magnetized TOV case ** wondering if one could use metric defined at cell centers. Roland says that this will currently use the wrong prolongation operators since currently cell centered quantities are always treated as cell averages by the prolongation operators ** trying to understand differences between Spritz and AsterX still * Lucas has core documentation written ** which interpolation interface to use, native CarpetX one or using Cactus interpolator interface ** Erik suggests to document that Cactus interpolator one ** some errors in multipatch interpolation ** found that Paraview can read OpenMD data using BP4, but right now crashes afterwards, Roland asks for clarification if it uses the OpenPMD plugin with BP4 backend or BP4 plugin * no updates from Michal * Allen finds that runs crash if using >1 OpenMP threads, with PreSync only. This is the same problem that Sam, Gabriele and Luas encountered * Sam reported on the issues he encountered with PreSyncOnly mode, currently CarpetX has a WaveToy test that uses this and fails * Jay reported on TOV tests, trying to use metric defined at the center of the cell, still not quite seeing the correct modes. Roland suggests that the polynomial sampling prolongation operators at the cell center can be generated from the templated code, but currently are not. * no updates from Lorenzo Issues: * there seems to be an issue with OpenMP and certain presync modes, seen by Sam, Gabriele, and Lucas Yours, Roland -- My email is as private as my paper mail.
