Detailed Description

compute stress tensors given point load on semi-infinite domain

vtkPointLoad is a source object that computes stress tensors on a volume. The tensors are computed from the application of a point load on a semi-infinite domain. (The analytical results are adapted from Saada - see text.) It also is possible to compute effective stress scalars if desired. This object serves as a specialized data generator for some of the examples in the text.

Member Function Documentation

static int vtkPointLoad::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageAlgorithm.

virtual int vtkPointLoad::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageAlgorithm.

static vtkPointLoad* vtkPointLoad::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkImageAlgorithm.

virtual vtkObjectBase* vtkPointLoad::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkImageAlgorithm.

vtkPointLoad* vtkPointLoad::NewInstance ( ) const

Reimplemented from vtkImageAlgorithm.

void vtkPointLoad::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 vtkImageAlgorithm.

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

Construct with ModelBounds=(-1,1,-1,1,-1,1), SampleDimensions=(50,50,50), and LoadValue = 1.
