Detailed Description

template<int dim, int spacedim>
class OpenCASCADE::ArclengthProjectionLineManifold< dim, spacedim >

A Boundary object based on OpenCASCADE TopoDS_Shape objects which have topological dimension equal to one (TopoDS_Edge or TopoDS_Wire) where new points are located at the arclength average of the surrounding points. If the given TopoDS_Shape can be casted to a periodic (closed) curve, then this information is used internally to set the periodicity of the base ChartManifold class.

This class can only work on TopoDS_Edge or TopoDS_Wire objects, and it only makes sense when spacedim is three. If you use an object of topological dimension different from one, an exception is throw.

In debug mode there is an additional sanity check to make sure that the surrounding points actually live on the Manifold, i.e., calling OpenCASCADE::closest_point() on those points leaves them untouched. If this is not the case, an ExcPointNotOnManifold is thrown.

Member Function Documentation

pull_back()

template<int dim, int spacedim>

Point< 1 > OpenCASCADE::ArclengthProjectionLineManifold< dim, spacedim >::pull_back ( const Point< spacedim > &  space_point ) const

virtual

Given a point on real space, find its arclength parameter. Throws an error in debug mode, if the point is not on the TopoDS_Edge given at construction time.

Implements ChartManifold< dim, spacedim, 1 >.

push_forward()

template<int dim, int spacedim>

Point< spacedim > OpenCASCADE::ArclengthProjectionLineManifold< dim, spacedim >::push_forward ( const Point< 1 > &  chart_point ) const

virtual

Given an arclength parameter, find its image in real space.

Member Data Documentation

curve

template<int dim, int spacedim>

Handle_Adaptor3d_HCurve OpenCASCADE::ArclengthProjectionLineManifold< dim, spacedim >::curve

private

A Curve adaptor. This is the one which is used in the computations, and it points to the right one above.

Definition at line 309 of file boundary_lib.h.

tolerance

template<int dim, int spacedim>

const double OpenCASCADE::ArclengthProjectionLineManifold< dim, spacedim >::tolerance

private

Relative tolerance used in all internal computations.

Definition at line 314 of file boundary_lib.h.

length

template<int dim, int spacedim>

const double OpenCASCADE::ArclengthProjectionLineManifold< dim, spacedim >::length

private

The total length of the curve. This is also used as a period if the edge is periodic.
