Issues with intra-element discontinuities in PIC-FEM The classical finite element method (FEM) has been widely used to simulate diverse problems in engineering. Unlike most engineering problems, geological simulations are dominated by emergence of geometrical structures due to the non-linear processes involved.

As mentioned, packages can be installed directly from our conda channel. You may however want to build your own package at some point in the future or you may want to fix some of ours by submitting a Pull Request on github (You are more welcome to do so...) The following goes through the steps of building a conda package for Badlands which contains Python and Fortran code. This is relatively advanced but not really difficult.

Version control systems and online-communities such as Github have made contributing to the development of opensource software incredibly easy. That is assuming that people get over their initial fear of sharing their code!  In this short blog post I go through how to submit a pull request to one of our repository. Do not fear and join us for some fun!

Conda packages are now available for most of the underworldcode suite of software (Underworld, UWGeodynamics, Lavavu, Stripy) from the geo-down-under conda channel. Let’s face it. Users don’t want to spend time compiling code on their machine. It is time consuming, requires some specific skills and creates unnecessary hurdles in a workflow.

Underworld 2.10 has been released! Available via docker (recommended), pip and source code . See here for more information on each install process. For a quick taste of Underworld try our binder cloud resource, a temporary "virtual sandbox" to explore the release and example models. Click the button below. This new release includes the following: Enhancements Using UWGeodynamics-2.10.1, see here.

We've been busy creating the next major release of Stripy. To refresh your memory, Stripy is a Python tool for triangulating scattered points either in Cartesian coordinates or on the sphere. It wraps a bunch of Fortran codes in a neat, object-oriented Python interface that can be used for many geographical applications. What's new? Spline tension - a lot of data transformations in Stripy are underpinned by cubic splines (e.g.

Meghan S Miller, Louis Moresi, Research School of Earth Sciences, Australian National University A new study by an international team of scientists has found lockdown measures to stop the spread of COVID-19 led to a 50 per cent reduction in seismic noise observed around the world. It is the largest reduction in human-generated noise ever observed globally.

Meghan S. Miller, Australian National University and Louis Moresi, Australian National University How we built a simple dashboard using Github actions with open source software and openly available (FAIR) data. We recently wrote an article in The Conversation that shows how the Australian Seismometers in schools network registers the pulse of Australian life through changes in the seismic noise

Meghan S. Miller, Australian National University and Louis Moresi, Australian National University Our responses to the COVID-19 pandemic have dramatically changed human activity all over the world. People are working from home, schools are closed in many places, travel is restricted, and in some cases only essential shops and businesses are open. Scientists see signs of these changes wherever they look.

The Underworld team would like to congratulate Bénédicte Cenki-Tok and co-authors at the University of Sydney and the University of Montpellier on their recent publication, B. Cenki-Tok, P.F. Rey, D. Arcay;
