n in the case of "op_copy". The problem here likely resulted in confusion due to the operator being badly named (https://martinfowler.com/bliki/TwoHardThings.html). In arrangements/Carpet/CarpetLib/src/operators.hh, the implication is that the "copy" in op_copy refers to the time interpolation only, but the code in patched in the above commit assumes that "copy" means don't interpolate at all. It's not clear how this can make sense when the data comes from another refinement level, which will always have a different resolution, but maybe there is some case where this would have made sense. Erik, should this commit be merged to master? -- Ian Hinder http://members.aei.mpg.de/ianhin ___ Users mailing list Users@einsteintoolkit.org http://lists.einsteintoolkit.org/mailman/listinfo/users

Re: [Users] defining a grid function constant in time

regridding? By not prolongating the refinement boundaries, it's not clear how the "new" bits of the grid are supposed to be filled when the fine grids move. Could this be the problem? If you give the gridfunction 3 timelevels and remove "prolongation=none", do the NaNs go away? -- Ian Hinder http://members.aei.mpg.de/ianhin ___ Users mailing list Users@einsteintoolkit.org http://lists.einsteintoolkit.org/mailman/listinfo/users

Re: [Users] compilation on marenostrum 4

. For submissions, you can: 1. Ask on the list; 2. Create a bitbucket pull request; or 3. Create a ticket on TRAC. Up to you! Probably (2) is the preferred option. -- Ian Hinder http://members.aei.mpg.de/ianhin ___ Users mail
