#2586: new cGH field cctk_patch
Reporter: Roland Haas Status: open Milestone: Version: development version Type: enhancement Priority: minor Component: Cactus
Comment (by Roland Haas):
Note that to find out the total number of patches (maps) one still has to call the aliased functon `GetMaps`. Not sure if there is a legit use for that information though (there is also not official way to find out the total number of components [not MPI ranks]). Also note that the assumption `cctk_patch == 0` → Cartesian patch is most likely not true for eg the 6 patch cubed sphere system (which has no Cartesian block in the center). The function to query this would be `MultiPatch_MapIsCartesian` in the `Coordinates` thorn (which only requires knowledge of `cctk_patch` and of course calls it `map`).
