Detailed Description

PURPOSE: Sets boundary conditions (quantities in ghost zones) for the gravitational potential on each edge of a Grid. See comments at start of bvals_mhd.c for more details. The only BC functions implemented here are for:

Function Documentation

void bvals_grav ( DomainS *  pD  ) 

Calls appropriate functions to set ghost zones.

The function pointers (*_GBCFun) are set during initialization by bvals_grav_init() to be one of the functions corresponding to reflecting or periodic. If the left- or right-Grid ID numbers are >= 1 (neighboring grids exist), then MPI calls are used.

Order for updating boundary conditions must always be x1-x2-x3 in order to fill the corner cells properly
