inverse reasoning Jan 25, 2014

Most people, if you describe a train of events to them will tell you what the result will be. There are few people, however that if you told them a result, would be able to evolve from their own inner consciousness what the steps were that led to that results. This power is what I mean when I talk of reasoning backward. Sherlock Holmes, Sir Arthur Conan Doyle (1887)

Open Access Tools for Geoscience Education Jan 22, 2014

I was invited to give a talk on VisibleGeology at UBC Open Access week. My talk was entitled 'Open Access Tools for Geoscience Education'.

SimPEG Play - DC Resistivity Inversion Jan 17, 2014

Working to incorporate DC resistivity inversions in the new SimPEG framework.

SimPEG Framework Design Jan 16, 2014

Working to create a better design for geophysical workflows using SimPEG. The discussions have resulted in an overhaul of the current framework.

SimPEG Tutorial - Creating a Mesh Jan 10, 2014

In this tutorial we will go over creating a mesh, and the basics of numbering, counting, and naming conventions. With these skills you can move faster, and move between different meshes (hopefully) with ease!

SimPEG Play - Anisotropic Block Jan 09, 2014

Playing with anisotropy in SimPEG.

SimPEG Tutorial - Linear Problem Jan 06, 2014

In this tutorial we will create a simple linear problem from scratch using the SimPEG framework.

There are two different forms of Richards equation that differ on how they deal with the non-linearity in the time-stepping term. Here we reproduce results from a seminal paper, and show the ease with which you can do this in SimPEG and Richards python packages.
