  1. 2018 Introduction to thermal-mechanical lithosphere models with surface processes

    04 Feb 2021 | Contributor(s): Louis Moresi, Romain Beucher

    Surface processes including erosion, transport and sedimentation have the potential to strongly influence crustal and lithospheric deformation whether passively, through isostatic response, or more actively by affecting the thermal structure, the potential energy field, and / or the local stress...

  2. 2018 Pythonic Geodynamics

    04 Feb 2021 | Contributor(s): Gabriele Morra, David A. Yuen, Sang-Mook Lee

    Students and young researchers who want to learn to use computational tools for geodynamic modeling have the option to choose among a wide range of numerical tools. I will show how Python and its libraries represent an easy-to-use platform for self-learning, with performance close to compiled...

  3. 2017 Geodynamic modeling with staggered finite differences and marker in cell: theory, teaching and examples

    04 Feb 2021 | Contributor(s): Taras Gerya

    Numerical modeling of geodynamic processes is an essential approach in both science and industry with ever- growing demand and high efficiency/cost ratio. Current trend in geodynamic modeling is to develop universal approaches with potentially unlimited number of applications. One simple...

  4. 2017 Introduction to the spectral-infinite-element method

    04 Feb 2021 | Contributor(s): Hom Nath Gharti, Jeroen Tromp

    The governing equations for the elastic-gravitational deformation of an Earth model involve a perturbed gravitational potential. The gravitational potential is governed by Poisson’s equation inside the Earth and by Laplace’s equation in the rest of space. The infinite domain...

  5. 2016 Software Practices in Computational Science Communities – an Overview

    04 Feb 2021 | Contributor(s): Anshu Dubey

    Scientific code developers typically adopt software processes derived from the mainstream (non-scientific) community when continuing without them becomes impractical. However, many software best practices need modification and/or customization, partly because the codes are used for...

  6. 2016 Resolution analysis by random probing

    04 Feb 2021 | Contributor(s): Andreas Fichtner, Tristan van Leeuwen

    We present a new method for resolution analysis in tomography, based on stochastic probing of the Hessian or resolution operators. Key properties of the method are (i) low algorithmic complexity and easy implementation, (ii) applicability to any tomographic technique, including full-waveform...

  7. 2016 Statistical and computational challenges of constraining greenhouse gas budgets

    04 Feb 2021 | Contributor(s): Anna M. Michalak

    Predicting future changes to the global carbon cycle (and therefore climate) and quantifying anthropogenic emissions of greenhouse gases (GHGs) both require an understanding of net GHGs emissions and uptake across a variety of spatial and temporal scales.  This talk will explore some of the...

  8. 2016 Uncertainty Quantification in Computational Models of Physical Systems

    04 Feb 2021 | Contributor(s): Habib Najm

    Models of physical systems typically involve inputs/parameters that are determined from empirical measurements, and therefore exhibit a certain degree of uncertainty. Estimating the propagation of this uncertainty into computational model output predictions is crucial for purposes...

  9. 2016 Verification, Validation, and Predictive Capability: What's What?

    04 Feb 2021 | Contributor(s): William Oberkampf

    Engineering and geosciences organizations must increasingly rely on computational simulation for the design, predicted response, and performance of manmade and natural systems. Computational analysts,  decision makers, and regulatory authorities who rely on simulation should have practical...

  10. 2015 ASPECT: From Benchmarking to 3D Subduction Applications

    04 Feb 2021 | Contributor(s): Cedric Thieulot, Anne Glerum, Menno Fraters, Wim Spakman

    ASPECT, the Advanced Solver for Problems in Earth's Convection, is an extensible open source, community supported code.  The code is being applied to a broad range of problems in geodynamics.  This talk will explore the community's efforts in benchmarking, implementation of...

  11. 2015 An introduction to Virtual Quake

    04 Feb 2021 | Contributor(s): Kasey Schultz, John Wilson

    This webinar will introduce Virtual Quake, a boundary element code that performs simulations of fault systems based on stress interactions between fault elements to understand long term statistical behavior. The webinar will cover:Downloading, installing and running Virtual...

  12. 2015 Simulating seismic wave propagation with SW4

    04 Feb 2021 | Contributor(s): Anders Petersson

    This webinar describes how to use the SW4 code to simulate ground motion due to earthquakes. After a brief overview of the numerical method, we describe how to set up a simulation in terms of seismic sources, the material model, visco-elastic attenuation, and topography. We also present some of...

  13. 2015 An introduction to BurnMan - a mineral physics toolkit

    03 Feb 2021 | Contributor(s): Sanne Cottar, Timo Heister, Bob Myhill, Ian Rose, Cayman Unterborn

    In this webinar we will introduce the extensible, open source mineral physics toolkit BurnMan. This software allows the user to calculate the elastic and thermodynamic properties of rocks, minerals, fluids and melts based on the properties of end-member phases. BurnMan is bundled with...
