bound

Signature:

bound(time, nvar, ng, valbig, mitot, mjtot, mptr, aux, naux)

Arguments:

integer, intent(in):

• nvar: Number of solution variables.
• ng: Number of ghost cells in each direction (width of boundary region).
• mitot: Horizontal dimension of the grid, including ghost cells.
• mjtot: Vertical dimension of the grid, including ghost cells.
• mptr: Pointer to the descriptor of the input grid.
• naux: Number of aux variables.

double precision, intent(in):

• time: Time at which to fill the ghost cells.
• aux(mitot,mjtot,naux): Values of aux variables on the input grid.

double precision, intent(inout):

• valbig(mitot,mjtot,nvar): Solution values on the input grid.

Description:

This routine sets the boundary values (ghost cells) for a given grid, specified by mptr, at level level. It fills the values for a region ng cells wide all the way around the border, in 4 rectangular strips.
