# Heat equation with harmonic source and Neumann boundary

Is there an analytic solution or series approach to the 2D time-dependent heat equation in a square with a harmonic source and Neumann boundary conditions $\nabla u.n=0$?

• You can use separation of variables to get a series solution. May 20, 2015 at 15:56
• could you post a pointer to a reference doing so!?
