NAME
Grid_getDomainBC
SYNOPSIS
Grid_getDomainBC(integer(OUT) :: boundary(LOW:HIGH,MDIM),
DESCRIPTION
Returns the boundary condition for each face of the domain The boundary conditions are defined in the header file constants.h, ie. OUTFLOW, REFLECTING, PERIODIC etc
ARGUMENTS
boundary - array returned holding boundary conditions, except when periodic,
if any of the faces of the block are on a physical boundary.
the first index of the array can take on values LOW or
HIGH, and the second index can be IAXIS, JAXIS or KAXIS
NOTES
The #define constants LOW, HIGH, IAXIS, JAXIS and KAXIS are defined in constants.h and are meant to ease the readability of the code. instead of boundary(2,3) = PERIODIC the code reads boundary(HIGH, KAXIS) = PERIODIC
