This class focuses on the numerical solution of problems arising in
the quantitative modeling of Earth systems. The focus is on continuum
mechanics problems as applied to geological processes in the solid
Earth, but the numerical methods have broad applications including in
geochemistry or climate modeling. We briefly review math and continuum
mechanics fundamentals, then discuss ordinary differential equations
(ODEs), and spend the majority of the class discussing finite
difference (FD) and finite element (FE) solutions to partial
differential equations (PDEs).
The class targets graduate students from the Earth sciences, and
consists of lectures and joint and individual computer lab exercises.
Grading is based on home work/programming project assignments, a final
project, and class participation.
This class was last taught in 2016 but lecture notes and problem
sets may be useful are are provided in individual chunks below
Prerequisites: None. Recommended: Intro Earth Science, Geodynamics.
