Underworld3 published in Journal of Open Source Software

The aim of underworld3 is to provide strong support to users in developing sophisticated mathematical models, and provide the ability to interrogate those models during development and at run-time. Underworld3 encodes the mathematical structure of the equations it solves in symbolic form.

New features of the surface-coupling framework in Underworld 2

New features of the surface-coupling framework in Underworld 2

Coupling in Underworld 2 Underworld 2's UWGeodynamic module enables the coupling of tectonics and surface processes models, most notably, with Underworld 2 handling the tectonics and Badlands (Salles, Ding, & Brocard, 2018) handling the surface processes. This coupling framework has been employed to study landscape evolution and topography

How many processors should we use to solve Problem X?

How many processors should we use to solve Problem X?

Parallel computation puts many CPUs to work on solving a problem much more quickly than one CPU alone. But this only works if the tasks are carefully scheduled and the additional CPUs are not waiting around for something to do. How do we choose the right number of processors for a given problem ?

Underworld Geodynamic Modelling Workshop. Perth, 7 May 2025

Underworld Geodynamic Modelling Workshop. Perth, 7 May 2025

You are invited to a full-day workshop on Underworld — a computational Geodynamics / Tectonics modelling framework. This is an excellent opportunity for researchers, students, and professionals interested in computational geodynamics and Earth science modelling to learn about Underworld.

Underworld and Singularity

Underworld and Singularity

TL; DR: Underworld is now Singularity-enabled, making it easier and somewhat quicker to use compared to traditional HPC installs. We demonstrate results using over 10,000 CPUs and more than one billion unknowns for solving the Stokes equation with Underworld 2.16

30 Years of Citcom, Ellipsis and Underworld

CITCOM is a geodynamics modelling code based on the finite element method that is designed for planetary evolution modelling where large spatial variations and strong non-linearities occur in the material properties.

The Dynamics of Continental Accretion

The Dynamics of Continental Accretion

In a recent paper [1], we used Underworld models to examine subduction congestion associated with the ingestion of a continental ribbon. The SE Australian geological record turned out to be a wonderful place to study this process. Here is a short summary of the work for a relatively non-technical audience
