Re: [FLASH-USERS] About gravity

There isn't currently a subroutine hook for this (add that to the
to-do list), but it shouldn't be hard: either add your external
potential to the one computed by the Poisson solver in
GravPotentialAllBlocks() or add the acceleration to the differenced
acceleration in GravAccelOneRow(). The latter approach is to be
preferred since it avoids issues with differencing at fine-coarse
boundaries.

Best,
Paul
