Detailed Description

Runtime bed state, one entry per LINK.

Sized to links rather than to the active engine's own elements (ARD cells, LARD parcels) because the bed does not move and does not subdivide: it is a property of the conduit, and every engine can address it by link index without agreeing on a mesh.

Warning

Under EULERIAN_ARD this means the bed exchanges with the link's VOLUME-WEIGHTED MEAN temperature, not cell by cell, so a bed under a long conduit cannot resolve a front the way the water above it does. That is a real loss of resolution against the reference (whose HTS elements map 1:1 onto channel elements) and it is recorded here rather than in a handoff because the next person to add a cell-resolved bed needs to find it attached to the array they would have to widen.

Member Data Documentation

cell_conc

std::vector<double> openswmm::BedZoneState::cell_conc

SPECIES-MAJOR [s * n_cells + c] — cell_phi's own layout, because the ARD binding walks both arrays in the same loop and two layouts in one loop is how a stride bug reads plausibly.

cell_n_species

int openswmm::BedZoneState::cell_n_species = 0

cell_temp

std::vector<double> openswmm::BedZoneState::cell_temp

[cell], °C

cells_seeded

bool openswmm::BedZoneState::cells_seeded = false

link_conc

std::vector<double> openswmm::BedZoneState::link_conc

[link * n_species + s], concentration in the bed water, in each species' own units. Species-minor to match node_mass_'s layout in the ARD store, which is the binding most likely to index it.

link_temp

std::vector<double> openswmm::BedZoneState::link_temp

[link], °C

n_species

int openswmm::BedZoneState::n_species = 0

seeded

bool openswmm::BedZoneState::seeded = false
