NAME

  Gravity_computeDt

SYNOPSIS

  Gravity_computeDt(integer(IN)        :: blockID,
                    real (OUT)         :: dt_grav,
                    integer(:)(INOUT)  :: dt_minloc(5))

DESCRIPTION

  Compute the timestep limiter due to the gravitational solver.

ARGUMENTS

  dt_grav:       Will Return the limiting timestep. Should be
                 set to a large value (1.D99) on input.
  dt_minloc(5):  An array to receive information about which
                 processor, block, and zone was responsible
                 for setting the limiting timestep.  The order
                 is i, j, k, b, p, where (i,j,k) = zone
                 indices, b = local block ID, and p = PE #.
                 This routine should only modify these values
                 if it changes dt_grav.
  blockID:       The local ID of the block to compute the
                 limiter on.
