NAME

  Grid_getGlobalIndexLimits

SYNOPSIS

  Grid_getGlobalIndexLimits(integer(OUT) :: globalIndexLimits(MDIM))

DESCRIPTION

  Gets the integer index dimensions of the entire grid 
  across all processors. Guardcells are not included.

  globalIndexLimits(IAXIS) = highest index of grid in i dir  
  globalIndexLimits(JAXIS) = highest index of grid in j dir   
  globalIndexLimits(KAXIS) = highest index of grid in k dir   

  (IAXIS, JAXIS and KAXIS are defined in constants.h
  and are set to 1,2 and 3 respectively)

  In an adaptive mesh, the highest index is returned as if
  the entire mesh was fully refined.

ARGUMENTS

  globalIndexLimits - returned array

EXAMPLE

   Example 1. UG.
   For a 2d problem with a uniform grid block size of 8 
   With 4 blocks laid out in a square (2x2) grid
 
   globalIndexLimits(IAXIS) = 16
   globalIndexLimits(JAXIS) = 16
   globalIndexLimits(KAXIS) = 1  !because only 2d

   Example 2. Paramesh
   For a 2d problem with block size of (8x8) and 
   maximum refinement level of 3, if the problem was
   initialized with one block then
 
   globalIndexLimits(IAXIS) = 32
   globalIndexLimits(JAXIS) = 32
   globalIndexLimits(KAXIS) = 1  !because only 2d

   if problem was initialized with 2 blocks along IAXIS
   and 1 block along JAXIS then

   globalIndexLimits(IAXIS) = 64
   globalIndexLimits(JAXIS) = 32
   globalIndexLimits(KAXIS) = 1  !because only 2d
