extend multipole gravity to interior #101

Closed zingale closed 5 years ago

zingale commented 7 years ago

multipole gravity was implemented primarily to allow for Dirchlet BCs for an isolated mass distribution with the MG solve. This simplified the construction. We should extend multipole to the interior since there could be some use cases for it.

this seems to be implemented on the gravity branch but needs to be tested

zingale commented 5 years ago

the original motivation was GPUs, but the multigrid solver works really well on GPUs now, so this is not a priority.
