+The resolution of the simulation can be changed by modifying the following fields contained in [https://clover.pas.rochester.edu/trac/astrobear/wiki/GlobalDataExplained global.data]:
+{{{
+MaxLevel          = 2            ! Maximum level for this simulation.
+GmX               = 32,          ! number of cells in x direction
+                    32,          ! number of cells in y direction
+                    32,          ! number of cells in z direction (set to 1 for 2D problems).
+
+}}}
+
+MaxLevel regulates the maximum amount of AMR levels, while GmX sets the number of cells in a fixed grid array.
+'''Warning:''' global.data contains another array entry, ''Domain%mGlobal'' which should usually be set to (1, 1, 1, GmX(1), GmX(2), GmX(3)), changing Gmx without modifying Domain%mGlobal as well could lead to instabilities.
