#include <itkFEMElement2DC0LinearQuadrilateralStrain.h>
4-noded finite element class in 2D space for linear elasticity problem
The ordering of the nodes is counter clockwise. That is the nodes should be defined in the following order:
3 (0,1) 2 (1,1) *---------------------—* | | | | | | | | | | | | *---------------------—* 0 (0,0) 1 (0,1)
This class combines the geometry of the FE problem defined in Element2DC0LinearQuadrilateral and the physics of the problem defined in Element2DStrain

CreateAnother method will clone the existing instance of this type, including its internal member variables.
Reimplemented from itk::LightObject.

Run-time type information (and related methods).
Reimplemented from itk::fem::Element2DStrain< Element2DC0LinearQuadrilateral >.

static |
Method for creation through the object factory.

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.
