bool | touchesDomain = false |
| | True if the patch abuts the domain boundary on any side, i.e. if any boundary-flux work is needed at all.
|
| |
|
int | hasLo [SpaceDim] = {D_DECL(0, 0, 0)} |
| | Per-direction flag: 1 if the patch abuts the lo domain face in that direction, 0 otherwise.
|
| |
|
int | hasHi [SpaceDim] = {D_DECL(0, 0, 0)} |
| | Per-direction flag: 1 if the patch abuts the hi domain face in that direction, 0 otherwise.
|
| |
|
Box | loBox [SpaceDim] |
| | Lo-side cell-centered box abutting the domain. Valid only when hasLo[dir] == 1.
|
| |
|
Box | hiBox [SpaceDim] |
| | Hi-side cell-centered box abutting the domain. Valid only when hasHi[dir] == 1.

Cached domain-boundary boxes for a single grid patch.
Precomputed in EBHelmholtzOp::defineStencils so that applyDomainFlux and fillDomainFlux can avoid recomputing EBArith::loHi (and its associated timer/box-arithmetic overhead) on every V-cycle. The boxes depend only on the problem domain and the grid layout, both of which are fixed once the operator has been defined.
