Detailed Description

This implicit function is the maximum of two (of more) implicit functions with which it is constructed. This results in an implicit function whose interior is the intersection of the interiors of the given implicit functions. For the maximum, it uses the smooth absolute value Ae(a,b) |a-b| max(a,b) = 0.5*(a+b + | a-b |)

Member Function Documentation

virtual Real SmoothIntersection::value

(

const RealVect &

a_point

)

const [virtual]

Return the value of the function at a_point.

Implements BaseIF.

virtual Real SmoothIntersection::derivative	(	const IntVect &	a_deriv,
		const RealVect &	a_point
	)			const [virtual]

return the partial derivative at the point

Reimplemented from BaseIF.

virtual BaseIF* SmoothIntersection::newImplicitFunction

(

)

const [virtual]

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