DOLFIN doesn't do this out of the box. You would have to develop your
own model using FFC and the tools that DOLFIN provides.

DOLFIN can solve explicit problem, although there is no simple demo for
explicit time stepping (we should add one). You just need to use FFC to
produce a header file to compute the mass matrix and RHS vector, and use
DOLFIN to assemble them. DOLFIN provides a function to lump the matrix
(FEM::lump(...)).
