Hi all,I'm trying to figure out how to use amrspace combined with load_amr_grids to create a decently complex amr structure for testing. However, I can't find any example of doing such a thing in any documentation or source. My attempt below fails in that it creates no level-0 grids, and also has the ordering of grids messed up grid 0 is level 4.Any advice on combining these two functions?Thanks,Sam
