Member Function Documentation

◆ resize()

void openswmm::hydstruct::WeirGroup::resize ( int n )

Resize WeirGroup columns while preserving existing row prefixes.

Sets count then resizes every declared vector; new numerical fields0, curve index-1 and can_surcharge1. Link indices value-initialize on growth. Allocation may leave partial resizing and invalidate borrowed element views.

Parameters

[in] n Nonnegative count; negative is unchecked before size_t conversion.

Member Data Documentation

◆ c_disch1

std::vector<double> openswmm::hydstruct::WeirGroup::c_disch1

Main discharge coefficient.

◆ c_disch2

std::vector<double> openswmm::hydstruct::WeirGroup::c_disch2

End section coefficient (trapezoidal)

◆ can_surcharge

std::vector<uint8_t> openswmm::hydstruct::WeirGroup::can_surcharge

Surcharge YES/NO (legacy Weir.canSurcharge): when NO and h1 >= hcrown, the head is capped at the weir opening height instead of switching to the equivalent-orifice formulation (legacy link.c weir_getInflow).

◆ cd_curve

std::vector<int> openswmm::hydstruct::WeirGroup::cd_curve

Optional Cd(head) curve index (legacy Weir.cdCurve), -1 none.

◆ count

int openswmm::hydstruct::WeirGroup::count = 0

◆ end_con

std::vector<double> openswmm::hydstruct::WeirGroup::end_con

End contraction factor.

◆ length_eff

std::vector<double> openswmm::hydstruct::WeirGroup::length_eff

Effective length used for surface-area computation (legacy Weir[k].length = max(200, 2·routeStep·sqrt(g·yFull))). Pre-computed at init; constant per simulation.

◆ link_idx

std::vector<int> openswmm::hydstruct::WeirGroup::link_idx

◆ road_surface

std::vector<int> openswmm::hydstruct::WeirGroup::road_surface

ROADWAY weir surface: 0 none, 1 PAVED, 2 GRAVEL.

◆ road_width

std::vector<double> openswmm::hydstruct::WeirGroup::road_width

ROADWAY weir road width (ft, legacy Weir.roadWidth)

◆ slope

std::vector<double> openswmm::hydstruct::WeirGroup::slope

V-notch slope or trap slope.

◆ surf_area

std::vector<double> openswmm::hydstruct::WeirGroup::surf_area

Most-recently-computed surface area (ft²), populated by computeWeirFlows and scattered to node surface-area accumulators by the non_conduit_fn callback. Matches legacy Weir[k].surfArea.

◆ weir_type

std::vector<int> openswmm::hydstruct::WeirGroup::weir_type

TRANSVERSE/SIDE/VNOTCH/TRAPEZOIDAL/ROADWAY (0..4)
