## Detailed Description

compute stress tensors given point load on semi-infinite domain

Date:
  2002/08/05 17:29:13

Revision:
  1.36

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

virtual const char* vtkPointLoad::GetClassName | ( |  | ) | `[virtual]`

| Reimplemented from vtkImageSource.

int vtkPointLoad::IsTypeOf | ( | const char * | type | ) | `[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 vtkImageSource.

virtual int vtkPointLoad::IsA | ( | const char * | type | ) | `[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 vtkImageSource.

vtkPointLoad* vtkPointLoad::SafeDownCast | ( | vtkObject * | o | ) | `[static]`

| Reimplemented from vtkImageSource.

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 vtkImageSource.

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

| Construct with ModelBounds=(-1,1,-1,1,-1,1), SampleDimensions=(50,50,50), and LoadValue = 1. Reimplemented from vtkObject.
