Hello Sahil,

unfortunately there is no example with Neumann boundary conditions for Advection-Diffusion equations.
But you can simply use a difference quotient to transform your Neumann boundary into a Dirichlet boundary (fixed temperature boundary) and update it every timestep with a setBoundaryValues method.
