+When creating the nested domain, one must keep in mind that the child domain is shifted toward north-east and depends on the number of ghost cells as illustrated by the (attempted) drawing below for nbghostcells=1 and nbghostcells=3

 Note that rectangular regions must be defined so that they are connected to a single parent grid. Hence, defining overlapping grids with the same refinement ratio will not work properly, boundary data exchange and update being only performed between root and child grids. Use of east-west periodic or north-fold boundary conditions is not allowed in child grids either. Defining for instance a circumpolar zoom in a global model is therefore not possible.
