To test scalability we run weak scaling tests on various HPC machines to check the numerical framework remains robust when pushing for higher fidelity models.

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.

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!

Sharing a workflow environment is also paramount if we want to make sure that reproducibility can be effectively tested. An environment management system such as conda allows us to do so.

Underworld 2.10 has dropped... kidding this is a benchmark model proposed by Schmalholz, 2011, A simple analytical solution for slab detachment.

Generating Voronoi diagrams and interpolating / smoothing with spline tensions are among a list of new features in Stripy 2.0

A new study by an international team of scientists found lockdown measures to stop the spread of COVID-19 led to a 50 per cent reduction in seismic noise around the world. The researchers, including Meghan Miller and Louis Moresi from ANU analysed datasets from over 300 seismic stations.

How we built a simple dashboard using Github actions with open source software and openly available (FAIR) data.

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;
