- First semester 2019 (On-campus)
Introduction to PDEs; first-order PDEs and characteristics, the advection equation, nonlinear equations. Classes of second-order PDEs; boundary and/or initial conditions for well-posed problems. The wave equation: exact solutions on infinite and finite spatial domains, other hyperbolic PDEs, reflection of waves. The heat equation: exact solutions on infinite domain, separation of variables for fixed and/or insulating boundary conditions. Finite-difference methods for ODEs, truncation error. Forward, backward and Crank-Nicolson numerical methods for the heat equation, truncation errors and stability analysis. Numerical methods for the advection equation; upwind differencing. Exact solutions of Laplace's equation in various domains. Numerical methods for Laplace's and Poisson's equation.
On completion of this unit students will be able to:
- Understand the role of partial differential equations in the mathematical modelling of physical processes;
- Solve a range of first-order partial differential equations including using the 'method of characteristics';
- Appreciate the properties of the three basic types of linear second-order partial differential equations, including suitable initial and/or boundary conditions;
- Understand the mathematical properties of the diffusion equation, wave equation and Laplace's equation and solve them exactly under some simple conditions;
- Analyse and interpret simple applications modelled by the advection equation, diffusion equation and Laplace's equation;
- Understand the principles of finite-difference approximation of ordinary and partial differential equations and appreciate the advantages and disadvantages of a range of useful numerical techniques, including their stability;
- Evaluate numerical solutions of some partial differential equations using computers, and display those results graphically.
