Outline

• Continuing our tour of three PDEs …

• The diffusion equation (time-varying temperature problem)
  • Constant coefficients: The heated bar
  • Variable coefficients: The insulated bar
  • A Neumann boundary condition
  • Animations of matplotlib plots
• The wave equation (second-order derivatives in time)
• An example of the wave equation in practice (from SCEC and SDSC)
