Detailed Description

This implicit function takes one implicit function and move it along a helix in 3D. In 2D the implicit function is simply returned.

In 3D, if a_vertical is false, the given function is restricted to the x-y plane (z = 0), and this restricted function is rotated around the z-axis at the specified rate as z changes.

In 3D, if a_vertical is true, the given function is restricted to the x-y plane (z = 0), but this x-y cross section is oriented vertically and swept in a helix at the specified rate.

In 2D, the given function is simply returned.

Constructor & Destructor Documentation

HelixIF() [1/3]

HelixIF::HelixIF	(	const BaseIF &	a_impFunc,
		const Real &	a_rate,
		const bool &	a_inside,
		const bool &	a_vertical = true
	)

Constructor specifying one implicit function to be rotated, the rotation rate, and whether the domain is on the inside (a_inside), i.e. where the function is negative.
