Vertical and horizontal discretization

Limits of the grid :

• imin =0 (always) : index of the first column
• jmin =0 (always) : index of the first row
• imax : index of the last column
• jmax : index of the last row

• kmax

  : number of layers

  • k=1 bottom layer
  • k=kmax surface layer

Horizontal grid

Vertical grid
