  1. Towards Seamless Interoperability of MPI-OpenMP Applications

    Publication
    A chasm exists between mathematical software libraries written for MPI-based applications and those written for OpenMP applications. Recently, however, PETSc enables the simple use of its MPI …

  2. The Well: a Large-Scale Collection of Diverse Physics Simulations for Machine Learning

    Publication
    Machine learning based surrogate models offer researchers powerful tools for accelerating simulation-based workflows. However, as standard datasets in this space often cover small classes of physical behavior …

  4. A new provably stable weighted state redistribution algorithm

    Publication
    We propose a practical finite volume method on cut cells using state redistribution. Our algorithm is provably monotone, total variation diminishing, and GKS (Gustafsson, Kreiss, Sundström) stable in …

  5. Implicit Adaptive Mesh Refinement for Dispersive Tsunami Propagation

    Publication
    We present an algorithm to solve the dispersive depth-averaged Serre–Green–Naghdi equations using patch-based adaptive mesh refinement. These equations require adding additional higher derivative terms …

  6. A Weighted State Redistribution Algorithm for Embedded Boundary Grids

    Publication
    State redistribution is an algorithm that stabilizes cut cells for embedded boundary grid methods. This work extends the earlier algorithm in several important ways. First, state redistribution is …

  7. Towards Adaptive Simulations of Dispersive Tsunami Propagation from an Asteroid Impact

    Publication
    The long-term goal of this work is the development of high-fidelity simulation tools for dispersive tsunami propagation. A dispersive model is especially important for short wavelength …
