NAME
Grid_getBlkBoundBox
SYNOPSIS
Grid_getBlkBoundBox(integer(IN) :: blockId,
real(OUT) :: boundBox(2, MDIM))
DESCRIPTION
Gets the physical domain bounding box of the block identified by blockId. For each dimension the left (lower or forward) physical coordinate of the block edge and the right (upper or back) physical coordinate of the block edge is returned. See arguments below for more detail.
ARGUMENTS
blockId -local block number
boundBox - returned array holding the boundBox coordinates in
each dimension
for readability, in constants.h we define IAXIS = 1, JAXIS = 2, KAXIS = 3
boundBox(1,IAXIS) = left edge coordinate of block in x direction
boundBox(2,IAXIS) = right edge coordinate of block in x direction
boundBox(1,JAXIS) = top edge coordinate of block in y direction
boundBox(2,JAXIS) = bottom edge coordinate of block in y direction
boundBox(1,KAXIS) = front edge coordinate of block in z direction
boundBox(2,KAXIS) = back edge coordinate of block in z direction
EXAMPLE
In 2 dimensions, if physical coordinates are ...

boundBox(1, IAXIS) = -0.5
boundBox(2, IAXIS) = 0.5
boundBox(1, JAXIS) = 0.0
boundBox(2, JAXIS) = 1.0
boundBox(1, KAXIS) = 1 !returned as 1 because only 2 dims
boundBox(1, KAXIS) = 1 !returned as 1 because only 2 dims
