Enumeration Type Documentation

MomentumCategory

enum class openswmm::dynwave::MomentumCategory : uint8_t

strong

Momentum category for branch-free per-category kernel dispatch.

Each conduit is classified once per Picard iteration (after geometry is computed). Per-category kernels have zero shape/type/state branches in their inner loops, enabling compiler auto-vectorization.

Enumerator
SKIP_DRY	DRY/UP_DRY/DN_DRY, aMid<=FUDGE, or is_closed.
MANNING_OPEN	Standard Manning, open channel (Froude-based sigma)
MANNING_CLOSED_FS	Manning, closed conduit, free surface.
MANNING_CLOSED_FULL	Manning, closed conduit, surcharged (fr=0, sig=0)
FORCE_MAIN_HW	Force main, Hazen-Williams friction.
FORCE_MAIN_DW	Force main, Darcy-Weisbach friction.
N_CATEGORIES

SurchargeMethod

enum class openswmm::dynwave::SurchargeMethod : int

strong

Surcharge method: EXTRAN (classic) or SLOT (Preissmann).

Enumerator
EXTRAN	Classic EXTRAN approach — dQ/dH for surcharged nodes.
SLOT	Preissmann slot — fictitious narrow slot above crown.
DYNAMIC_SLOT	Dynamic slot — slot width varies with flow conditions (experimental) Sharior, S., Hodges, B.R., & Vasconcelos, J.G. (2023). Generalized, Dynamic, and Transient-Storage Form of the Preissmann Slot. Journal of Hydraulic Engineering, 149(11), 04023046.
