  1. 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...

  2. 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...

  3. 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...

  4. 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...

  5. 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...

  6. 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...

  9. 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...

  10. 2015 An introduction to BurnMan - a mineral physics toolkit
