) | 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 | ) | [protected, virtual] |
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 [protected, virtual] |
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.

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 element Return the shape functions used to interpolate across the element
