#945: add higher order restriction parameter to cell-centerd Carpet ------------------------------------+--------------------------------------- Reporter: rhaas | Owner: Type: enhancement | Status: reopened Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Resolution: | Keywords: CarpetLib ------------------------------------+---------------------------------------
Comment (by rhaas):
The first two and the last point should be taken care of. The source region for the operator is now computed by shrinking each source box by the one sided stencil size minus one. Since the region is afterwards intersected with the interior of the destination, no unnecessary restrictions are performed.
For point 3 I have the suspicion that it should be possible to coerce the existing vertex centered prolongation operators into service as cell centered restriction operators.
