Detailed Description

This implicit function specifies a sphere.

Constructor & Destructor Documentation

TylerChannelIF() [1/3]

TylerChannelIF::TylerChannelIF	(	const Real &	a_x1,
		const Real &	a_x2,
		const Real &	a_y1,
		const Real &	a_y2,
		const Real &	a_yDomainLength
	)

A C-infinity contraction/expansion channel.

The geometry is centered at [x_M,y_M] = [(a_x1+a_x2)/2,yDomainLength/2] and is symmetric about y = y_M. The size of the channel goes from 2*a_y1 to 2*a_y2 as x goes from -infinity to infinity.

The boundary is given by:

y(x)     = y_M +/- yDist(x)
yDist(x) = a_y1*(1-frac(x)) + a_y2*frac(x)
frac(x)  = (tanh(theta(x)) + 1) / 2
theta(x) = 4 * (x - x_M)/(a_x2 - a_x1)
