execute()

void openswmm::groundwater::GWSolver::execute	(	SimulationContext &	ctx,
		double	dt,
		double	max_evap,
		const double *	infil_rate,
		const double *	sw_head,
		const double *	frac_perv,
		const double *	perv_evap_rate
	)

Compute groundwater for all subcatchments (batch).

Steps (per subcatchment, all independent → vectorisable):

1. Compute upper zone percolation — batch exp() + multiply
2. Compute lateral GW flow — batch pow() + arithmetic
3. Compute deep percolation — batch multiply
4. Compute ET from upper/lower zones — batch clamp
5. Euler step: θ += dθ/dt * dt, H += dH/dt * dt — batch add

Parameters

ctx	Simulation context.
dt	Timestep (seconds).
max_evap	Maximum evaporation rate (ft/sec, scalar broadcast).
infil_rate	Per-subcatchment infiltration rate (ft/sec over full area).
sw_head	Per-subcatchment surface water head (ft).
frac_perv	Per-subcatchment pervious fraction (0-1).
perv_evap_rate	Per-subcatchment pervious evap rate already exerted (ft/sec over full area).
