Cell Indexing
MvMf6 use the same i-j-k indexing system as used by Modflow 6.
The i-j-k Index System for Cells
For a Modflow 6 model with structured discretization (DIS grid)
The index i runs along a row.
The index j runs along a column.
The index k increases from one layer to the next, counting from top to bottom.
The i-j-k Index System for Gridlines
For a model with Structured Discretization (DIS grid) MvMf6 can display 3 gridline sets defined respectively by the indices i, j, and k. These gridline sets are illustrated below.
