Member Function Documentation

computeAll()

void openswmm::inflow::InflowSolver::computeAll	(	SimulationContext &	ctx,
		double	current_date,
		double	dt )

Compute all external + DWF inflows and add to node lateral flow.

Batch operations:

1. Batch timeseries lookup for all ext inflows (gather from tables)
2. Batch pattern factor computation (vectorisable index arithmetic)
3. Batch multiply: inflow = conv * (ts_value * scale + baseline * pat)
4. Scatter-add to node lat_flow array

Parameters

ctx	Simulation context.
current_date	Current absolute date (decimal days).
dt	Timestep (seconds).

Here is the call graph for this function:

refreshPatterns()

void openswmm::inflow::InflowSolver::refreshPatterns

(

const SimulationContext &

ctx

)

Re-copy time-pattern factors from the context into the solver's per-step lookup cache.

init copies ctx.patterns into a private cache for fast per-step DWF/external-inflow scaling. A runtime pattern edit (swmm_pattern_set_factors) mutates ctx.patterns only, so the C API calls this to refresh the cache and let mid-run pattern changes take effect on the next step. Pattern count is assumed unchanged.

Parameters

ctx	Simulation context holding the authoritative pattern data.
