Dirac delta function on the lhs of variational problem

Asked by mattia

Hi,
I am a newbie to Fenics; I am currently simulating the mechanical behavior of a plate using dolfin and I found extremely useful the PointSource class in order to implement nodal forces on the plate.
Unfortunately, I now have to introduce also nodal stiffness and mass; as I introduced the delta function in the rhs, I am looking (without results) for a way to emulate this behavior on the lhs side.

Is there a way to implement this using PointSource?
