node(adjxlo,mptr)

Type: Pointer to storage

Target created in: prepadj (new routine, modeled after prepf)

Target destroyed in: putspadj (new routine, modeled after putsp)

Description: Target is an array of integers along the left boundary, corresponding to ghost cells. Entries describe the relation of ghost cells to other grids at the same level, with possible values:

  • madj, pointer to grid at the same level the contains this ghost cell, if such a grid exists.
  • 0, if the ghost cell is interior, but does not overlap a grid of the same level.
  • -1, if the ghost cell is exterior to the domain.
node(adjxhi,mptr)

Type: Pointer to storage

Description: Same function as node(adjxlo,mptr), but for ghost cells along the right boundary.

node(adjylo,mptr)

Type: Pointer to integer data

Description: Same function as node(adjxlo,mptr), but for ghost cells along the bottom boundary.

node(adjyhi,mptr)

Type: Pointer to integer data

Description: Same function as node(adjxlo,mptr), but for ghost cells along the top boundary.
