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.

Member Function Documentation

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

Return the value of the function at a_point.

Implements BaseIF.

virtual Real IntersectionIF::value ( const IndexTM< Real, GLOBALDIM > &  a_point  )  const [virtual]

Return the value of the function at a_point (of type INdexTM).

Reimplemented from BaseIF.

virtual IndexTM<Real,GLOBALDIM> IntersectionIF::normal ( const IndexTM< Real, GLOBALDIM > &  a_point  )  const [virtual]

Return the normalized gradient of the function at a_point. The gradients and normals are based on value, which yields outward-pointing normals (which is different the computational computation elsewhere in Chombo).

Reimplemented from BaseIF.

virtual Vector< IndexTM<Real,GLOBALDIM> > IntersectionIF::gradNormal ( const IndexTM< Real, GLOBALDIM > &  a_point  )  const [virtual]

Return the gradient of the normal at a_point.

Reimplemented from BaseIF.

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

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

Implements BaseIF.

void IntersectionIF::findClosest ( const IndexTM< Real, GLOBALDIM > &  a_point,
int &  closestIF 
) const

virtual bool IntersectionIF::fastIntersection ( const RealVect a_low,
const RealVect a_high 
) const [virtual]

Reimplemented from BaseIF.

virtual GeometryService::InOut IntersectionIF::InsideOutside ( const RealVect a_low,
const RealVect a_high 
) const [virtual]

Reimplemented from BaseIF.

void IntersectionIF::operator= ( const IntersectionIF a_inputIF  )  [inline, private]
