### Learning Outcomes

On successful completion of this module students should be able to:

Make an appropriate choice of numerical method (finite difference, finite element, hybrid) for a given linear elliptic, parabolic or hyperbolic PDE.

Discretise partial differential equations of arbitrary order using finite difference methods.

Use analytical techniques to determine the stability criterion for, and demonstrate consistency of, a finite difference scheme for a second order linear PDE and determine the local truncation error.

Derive the variational formulation for a given boundary value problem, and obtain the associated finite element discretisation.

Determine an appropriate set of shape functions with which to obtain the finite element approximation.

Implement a finite difference scheme in a Python environment to solve a two-dimensional hyperbolic PDE with boundary conditions.

Implement the finite element method in a Python environment to solve a one-dimensional boundary value problem.

Perform error and convergence analysis on finite difference and finite element schemes in a Python environment.

### Brief description

This module provides an introduction to numerical methods for solving partial differential equations of elliptic, parabolic and hyperbolic type. The analytical basis and numerical implementation of both finite difference and finite element methods are covered. Concepts such as consistency, convergence and stability of numerical methods will be discussed.

### Content
