-== Definition of grid hierarchy
+== Definition of the grid hierarchy
 An additional text file "AGRIF_FixedGrids.in" is required at run time. This is where the grid hierarchy is defined. An example of such a file, here taken from the VORTEX test case, is given below:

 The first line indicates the number of zooms (1). The second line contains the starting and ending indices in both directions on the root grid (19 38 19 38) followed by the space and time refinement factors (3 3 3). The last line is the number of child grid nested in the refined region (0). A more complex example with telescoping grids can be found below and in the cfgs/AGRIF_DEMO/EXPREF reference configuration directory (NEMO 4.0 only).

 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.

 == Namelist options
 Each child expects to read its own namelist so that different numerical choices can be made (these should be stored in the form 1_namelist_cfg, 2_namelist_cfg, etc... according to their rank in the grid hierarchy). Consistent time steps and number of steps with the chosen time refinement have to be provided. Specific to AGRIF is the following block:
