The equation is not self-adjoint. One way to proceed it is to discretize only the space part of the problem with finite elements. This leaves you with a system of coupled ordinary differential equations in time, wich you solve with finite differences. If you want unconditional stability for all time step sizes, you will need an implicit scheme. See Strang and Fix, chapter 7. -- --Pierre Asselin, Magnetoresistive Head Engineering, Applied Magnetics. pa@appmag.com the usual disclaimers apply.
