## Learning outcomes

After successful completion of the course, the student is expected to be able to:

• Apply the equations of continuum mechanics to geodynamical problems.
• Code one- and two-dimensional finite difference and spectral models of linear systems using MATLAB.
• Describe the differences and limitations of different numerical techniques and choose the most appropriate method accordingly.
• Explain the difference between Dirichlet and Neumann boundary conditions.
• Use the commercial code Comsol Multiphysics to solve a variety of dynamical problems.
• Produce visualisation of the output (graphs, contour plots, movies, etc.).

## Content

Finite difference and spectral methods. Introduction to Comsol Multiphysics (commercial finite element code).
Comparison of analytical and numerical solutions: heat equation, flexure of thin and thick plates, fluid flow. Asthenospheric counter-flow model. Post-glacial rebound. Diapirism as Rayleigh-Taylor instability. Thermal convection. One-dimensional flow with constant and variable viscosity. Shear heating in Couette flow and thermal run-away instability. Faulting, friction, and simple earthquake models. Stress diffusion.

## Instruction
