Detailed Description

This is the base class for an implicit function specification of geometry. All that is needed is a constructor/destructor, a method to give the value of the function at any point in space (in 2D or 3D), and a factory method (these will probably all be very similar).

Member Function Documentation

virtual Real BaseIF::value ( const RealVect & a_point ) const

pure virtual

Return the value of the function at a_point. When delineating a domain, the level set value=0 represents the boundary and value<0 is inside the fluid.

Implemented in DataFileIF, PolynomialIF, ReferenceHeightIF, TransformIF, LatheIF, GaussianIF, RhodoneaIF, TorusIF, TiltedCylinderIF, BilinearIF, GaussianSphereIF, MultiSphereIF, PlaneIF, ComplementIF, EllipsoidIF, PolarIF, SphereIF, HelixIF, HelicoilIF, TylerChannelIF, SumIF, IntersectionIF, UnionIF, MollifyIF, DEMIF, and SphereArrayIF.

Referenced by value(), and ReferenceHeightIF::value().

virtual Real BaseIF::value ( const IndexTM< Real, GLOBALDIM > & a_point ) const

inlinevirtual

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

Reimplemented in ReferenceHeightIF, TransformIF, GaussianSphereIF, ComplementIF, BilinearIF, MollifyIF, SumIF, IntersectionIF, and UnionIF.

References MayDay::Abort(), and LARGEREALVAL.

virtual BaseIF* BaseIF::newImplicitFunction ( ) const

pure virtual

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

Implemented in DataFileIF, ReferenceHeightIF, PolynomialIF, TransformIF, LatheIF, ComplementIF, GaussianIF, GaussianSphereIF, RhodoneaIF, TorusIF, TiltedCylinderIF, BilinearIF, SumIF, MultiSphereIF, PlaneIF, EllipsoidIF, PolarIF, SphereIF, HelixIF, IntersectionIF, MollifyIF, UnionIF, HelicoilIF, TylerChannelIF, DEMIF, and SphereArrayIF.

virtual void BaseIF::boxLayoutChanged	(	const DisjointBoxLayout &	a_newBoxLayout,
		const RealVect &	a_dx
	)

inlinevirtual

Inform the implicit function, IF, of a BoxLayout change in the application that is using it. If the implicit function uses distributed data, this gives it a chance to react to the spatial layout of the application that is using it.

This is a empty implementation for IFs that don't need this functionality.

Reimplemented in ReferenceHeightIF, LatheIF, TransformIF, ComplementIF, IntersectionIF, UnionIF, SumIF, HelixIF, MollifyIF, and HelicoilIF.

Referenced by HelicoilIF::boxLayoutChanged(), MollifyIF::boxLayoutChanged(), HelixIF::boxLayoutChanged(), ComplementIF::boxLayoutChanged(), TransformIF::boxLayoutChanged(), LatheIF::boxLayoutChanged(), and ReferenceHeightIF::boxLayoutChanged().
