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
