Detailed Description

cell represents a parabolic, 20-node isoparametric hexahedron

vtkQuadraticHexahedron is a concrete implementation of vtkNonLinearCell to represent a three-dimensional, 20-node isoparametric parabolic hexahedron. The interpolation is the standard finite element, quadratic isoparametric shape function. The cell includes a mid-edge node. The ordering of the twenty points defining the cell is point ids (0-7,8-19) where point ids 0-7 are the eight corner vertices of the cube; followed by twelve midedge nodes (8-19). Note that these midedge nodes correspond lie on the edges defined by (0,1), (1,2), (2,3), (3,0), (4,5), (5,6), (6,7), (7,4), (0,4), (1,5), (2,6), (3,7).

Member Function Documentation

static vtkQuadraticHexahedron* vtkQuadraticHexahedron::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual const char* vtkQuadraticHexahedron::GetClassName ( ) [virtual]

Reimplemented from vtkNonLinearCell.

static int vtkQuadraticHexahedron::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkNonLinearCell.

virtual int vtkQuadraticHexahedron::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkNonLinearCell.

static vtkQuadraticHexahedron* vtkQuadraticHexahedron::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkNonLinearCell.

void vtkQuadraticHexahedron::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[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.

Reimplemented from vtkNonLinearCell.
