The Grid functions return values related to the grid. Some grid functions may give different results in MODFLOW and PHAST for grids that appear the same. This is related to the differences way layers and rows are numbered and MODFLOW and PHAST.

PHAST and MODFLOW differ in how rows and layers are numbered as shown in figure 3. PHAST uses a standard right-hand coordinate system with the 1, 1, 1 layer, row, column in the closest lower left corner of the grid. MODFLOW is oriented with 1, 1, 1 in the furthest upper left corner.
