Detailed Description

This class provides an easy mechanism for adding a point quantities (Dirac delta function) to variational problems. The associated function space must be scalar in order for the inner product with the (scalar) Dirac delta function to be well defined. For each of the constructors, Points passed to PointSource will be copied.

Note: the interface to this class will likely change.

The documentation for this class was generated from the following files:
