Detailed Description

The kernel of ElementaryDeficit() along one source's wake axis.

d(x, rho) = At(x).amplitude exp(-rho^2 / (2 At(x).sigma^2)) for x >= XStart(), else 0. ElementaryDeficit() and the gridded builder both evaluate the kernel through this profile, so the formulas exist once (MENV-0009).

Constructor & Destructor Documentation

KernelProfile()

marenv::wake::KernelProfile::KernelProfile	(	const ElementarySource &	source,
		const KernelParams &	params
	)

Parameters

[in]	source	The elementary source; it must have a positive area.
[in]	params	The kernel parameters.

PeakAmplitude()

double marenv::wake::KernelProfile::PeakAmplitude	(	double	xFrom,
		double	xTo
	)		const

Upper bound of At(x).amplitude for x in [xFrom, xTo], x_start <= xFrom <= xTo, m.

The amplitude does not fall with x before x_p and does not rise beyond it (k >= 0, which Validate() requires of the fields), so the bound is its value at the end of the interval nearest to x_p, or d_mom where the interval holds x_p.
