// .NAME vtkPointLoad - compute stress tensors given point load on semi-infinite domain
// .SECTION Description
// 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.
// .SECTION See Also
