Grid_getGlobalIndexLimits()

subroutine Grid_getGlobalIndexLimits

(

integer

globalIndexLimits

)

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.

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 root 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
