Member Function Documentation

Float itk::fem::Element2DC0LinearLine::DistanceToLine ( const VectorType x,
const VectorType p1,
const VectorType p2,
Float t,
VectorType closestPoint 
) const

Distance of a point to a line.(Used in GetLocalFromGlobalCoordinates ).

virtual void itk::fem::Element2DC0LinearLine::GetIntegrationPointAndWeight ( unsigned int  i,
VectorType pt,
Float w,
unsigned int  order 
) const
virtual

Get the Integration point and weight

Implements itk::fem::Element.

virtual bool itk::fem::Element2DC0LinearLine::GetLocalFromGlobalCoordinates ( const VectorType globalPt,
VectorType localPt 
) const
virtual

Get parametric/local coordinates given global coordinates. The function returns true if the global coordinate is within the element else returns false. For a line, line length*1e-4 is used as the tolerance

Implements itk::fem::Element.

virtual const char* itk::fem::Element2DC0LinearLine::GetNameOfClass ( ) const
virtual

Run-time type information (and related methods).

Reimplemented from itk::fem::ElementStd< 2, 2 >.

Reimplemented in itk::fem::Element1DStress< Element2DC0LinearLine >, and itk::fem::Element2DC0LinearLineStress.

virtual unsigned int itk::fem::Element2DC0LinearLine::GetNumberOfIntegrationPoints ( unsigned int  order) const
virtual

Get the number of integration points

Implements itk::fem::Element.

virtual void itk::fem::Element2DC0LinearLine::Jacobian ( const VectorType pt,
MatrixType J,
const MatrixType pshapeD = ITK_NULLPTR 
) const
virtual

We need to provide our own implementation of calculating Jacobian, because the element lives in 2D space and has only one dimension. The default implementation of Jacobian in the Element base class is not correct since it assumes that the number of element dimensions is equal to the number of spatial dimensions.

Jacobian is a scalar for this element.

Reimplemented from itk::fem::Element.

virtual void itk::fem::Element2DC0LinearLine::PopulateEdgeIds ( void  )
protectedvirtual

Set the edge order and the points defining each edge

Implements itk::fem::Element.

virtual void itk::fem::Element2DC0LinearLine::PrintSelf ( std::ostream &  os,
Indent  indent 
) const
protectedvirtual

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::fem::ElementStd< 2, 2 >.

Reimplemented in itk::fem::Element1DStress< Element2DC0LinearLine >, and itk::fem::Element2DC0LinearLineStress.

virtual void itk::fem::Element2DC0LinearLine::ShapeFunctionDerivatives ( const VectorType pt,
MatrixType shapeD 
) const
virtual

Return the shape functions derivatives in the shapeD matrix

Implements itk::fem::Element.

virtual VectorType itk::fem::Element2DC0LinearLine::ShapeFunctions ( const VectorType pt) const
virtual

Methods related to the geometry of an elementReturn the shape functions used to interpolate across the element

Implements itk::fem::Element.
