This Demonstration solves the diffusion-advection-reaction partial differential equation (PDE)
in one dimension. The domain is discretized in space and for each time step
the solution at time is found by solving for from .

The boundary conditions supported are periodic, Dirichlet and Neumann. The solution can be viewed in
3D as well as in 2D. You can select the source term and the initial conditions from the menus in
the main display. Selected preconfigured test cases are available from the pull down menu. In the above
PDE represents the diffusion, represents the advection and the reaction.
