NAME
Grid_getSingleCellCoords
SYNOPSIS
Grid_getSingleCellCoords(integer(in) :: ind(MDIM),
integer(in) :: blockid,
integer(in) :: edge,
integer(in) :: beginCount,
real(OUT) :: coords(MDIM))
DESCRIPTION
Returns the coordinates of a single cell of a given block.
ARGUMENTS
ind - array holding the indices of the cell whose coordinates to return
blockid - local block number
edge - indicates if user wants the left, center or right edge of the block
options are LEFT_EDGE, RIGHT_EDGE, or CENTER. These constants are
defined in constants.h
beginCount : tells the routine where to start index counting. beginCount can
be set to INTERIOR or EXTERIOR. If INTERIOR is specified
guardcell indices are not included and index 1 is the first interior cell.
If EXTERIOR is specified
the first index, 1, is the left most guardcell. See example
below for more explanation. (For most of the FLASH architecture code,
we use EXTERIOR. Some physics routines, however, find it helpful
only to work on the internal parts of the blocks (without
guardcells) and wish to keep loop indicies
going from 1 to NXB without having to worry about finding
the correct offset for the number of guardcells.)
(INTERIOR and EXTERIOR are defined in constants.h)
coords : returned coordinates of the specificed cell
