PointSource
(V, p, magnitude=1.0)¶ Bases:
object
This class provides an easy mechanism for adding a point source (Dirac delta function) to the right-hand side vector in a variational problem. The associated function space must be scalar in order for the inner product with the (scalar) Dirac delta function to be well defined.
