An Eulerian PPM & PIC Code for Cosmological Hydrodynamics
A. Sornborger, B. Fryxell, K. Olson +1
We present a method for integrating the cosmological hydrodynamical equations including a collisionless dark matter component. For modelling the baryonic matter component, we use t…
Advancing Heliophysics and Space Weather Modeling through Open Science
C. Corti, M. M. Kuznetsova, M. A. Reiss +85
We present a community-wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potenti…
First use of synoptic vector magnetograms for global nonlinear force free coronal magnetic field models
Tilaye Tadesse, T. Wiegelmann, S. Gosain +2
The magnetic field permeating the solar atmosphere is generally thought to provide the energy for much of the activity seen in the solar corona, such as flares, coronal mass ejecti…
Simulations of Astrophysical Fluid Instabilities
A. C. Calder, B. Fryxell, R. Rosner +7
We present direct numerical simulations of mixing at Rayleigh-Taylor unstable interfaces performed with the FLASH code, developed at the ASCI/Alliances Center for Astrophysical The…
Full-disk nonlinear force-free field extrapolation of SDO/HMI and SOLIS/VSM magnetograms
Tilaye Tadesse, T. Wiegelmann, B. Inhester +3
Extrapolation codes in Cartesian geometry for modelling the magnetic field in the corona do not take the curvature of the Sun's surface into account and can only be applied to rela…
Verification of real-time WSA-ENLIL+Cone simulations of CME arrival-time at the CCMC from 2010-2016
A. M. Wold, M. L. Mays, A. Taktakishvili +3
The Wang-Sheeley-Arge (WSA)-ENLIL+Cone model is used extensively in space weather operations world-wide to model CME propagation. As such, it is important to assess its performance…
