Detailed Description

SoA storage for per-edge boundary conditions.

All arrays are flat 2D: indexed as [tri * 3 + edge_local] where edge_local ∈ {0,1,2}. Only meaningful for boundary edges (tri_nbr == -1), but allocated for all edges to avoid indirection in the flux loop.

Member Function Documentation

void openswmm::twoD::BoundaryData::resize ( int  n_edges )

Member Data Documentation

edge_bc_cum_flux

std::vector<double> openswmm::twoD::BoundaryData::edge_bc_cum_flux

Cumulative boundary flux (m³, positive = outflow from domain). Tracked for mass balance reporting.

edge_bc_flow

std::vector<double> openswmm::twoD::BoundaryData::edge_bc_flow

Prescribed discharge per metre of edge (m³/s/m) for SPECIFIED_FLOW edges. For time-varying: updated each step from timeseries.

edge_bc_flow_tseries

std::vector<int> openswmm::twoD::BoundaryData::edge_bc_flow_tseries

Timeseries index for time-varying SPECIFIED_FLOW. -1 = constant (use edge_bc_flow as-is), -2 = unresolved name, >= 0 = resolved table index into SimulationContext::tables.

edge_bc_flow_tseries_name

std::vector<std::string> openswmm::twoD::BoundaryData::edge_bc_flow_tseries_name

Timeseries name for deferred resolution (cleared after resolve).

edge_bc_head

std::vector<double> openswmm::twoD::BoundaryData::edge_bc_head

Prescribed total head for SPECIFIED_STAGE edges (m). For time-varying: updated each step from timeseries.

edge_bc_rating_curve

std::vector<int> openswmm::twoD::BoundaryData::edge_bc_rating_curve

Curve registry index for RATING_CURVE edges. -1 = unset, -2 = unresolved name, >= 0 = resolved curve index.

edge_bc_rating_curve_name

std::vector<std::string> openswmm::twoD::BoundaryData::edge_bc_rating_curve_name

Curve name for deferred resolution (cleared after resolve).

edge_bc_tseries

std::vector<int> openswmm::twoD::BoundaryData::edge_bc_tseries

Timeseries index for time-varying SPECIFIED_STAGE. -1 = constant (use edge_bc_head as-is), -2 = unresolved name, >= 0 = resolved table index into SimulationContext::tables.

edge_bc_tseries_name

std::vector<std::string> openswmm::twoD::BoundaryData::edge_bc_tseries_name

Timeseries name for deferred resolution (cleared after resolve).

edge_bc_type

std::vector<int8_t> openswmm::twoD::BoundaryData::edge_bc_type

Boundary condition type per edge (cast from BoundaryType)

edge_bed_slope

std::vector<double> openswmm::twoD::BoundaryData::edge_bed_slope

Bed slope for NORMAL_FLOW edges (dimensionless, >= 0). If 0.0 at parse time, auto-computed from bed geometry during init.
