Detailed Description

In 3D this is an approximation of a circle swept around a helix which is always in the plane normal to the tangent of the helix. If the slope of the helix is less than 1.0, this is achieved by sweeping an ellipse oriented vertically along a helix. If the slope is greater than or equal to 1.0, this is achieved by sweeping an ellipse oriented horizontally along a helix. The eccentricity of the ellipse is adjusted based on the slope.

In 2D this is an ellipse offset from the origin.

Constructor & Destructor Documentation

HelicoilIF::HelicoilIF ( const Real a_helixR,
const Real a_helixPitch,
const Real a_circleR,
const bool &  a_inside 
)

Constructor specifying the helix radius, pitch, radius of the swept circle, and whether the domain is on the inside (a_inside), i.e. where the function is negative.

HelicoilIF::HelicoilIF ( const HelicoilIF a_inputIF  )

Member Function Documentation

virtual Real HelicoilIF::value ( const RealVect a_point  )  const [virtual]

Return the value of the function at a_point.

Implements BaseIF.

virtual BaseIF* HelicoilIF::newImplicitFunction (  )  const [virtual]

Return a newly allocated derived class. The responsibility for deleting the memory is left to the calling function.

Implements BaseIF.

virtual void HelicoilIF::boxLayoutChanged ( const DisjointBoxLayout a_newBoxLayout,
const RealVect a_dx 
) [inline, virtual]

Pass this call onto the IFs contained in this IF class.

Reimplemented from BaseIF.
