[1] The Space Weather Modeling Framework (SWMF) provides a high-performance flexible framework for physics-based space weather simulations, as well as for various space physics applications. The SWMF integrates numerical models of the Solar Corona, Upper Atmosphere into a high-performance coupled model. The components can be represented with alternative(More)
[1] We present a three-dimensional (3-D) numerical ideal magnetohydrodynamics (MHD) model describing the time-dependent expulsion of a coronal mass ejection (CME) from the solar corona propagating to 1 astronomical unit (AU). The simulations are performed using the Block Adaptive Tree Solar-Wind Roe Upwind Scheme (BATS-R-US) code. We begin by developing a(More)
[1] In late October and early November 2003 a series of some of the most powerful solar eruptions ever registered shook the heliosphere. These ''Halloween storms'' damaged 28 satellites, knocking two out of commission, diverted airplane routes, and caused power failures in Sweden, among other problems. This paper presents a 4-day end-to-end simulation of(More)
A work strand planned by the Science Europe Working Group on Research Policy and Programme Evaluation aims at mapping the state of affairs in data collection and their use at European funding and research organisations. In particular, the project identifies and proposes solutions for issues experienced by the Member Organisations (MO) regarding collection,(More)
Space-environment simulations, particularly those involving space plasma, present significant computational challenges. Global computational models based on magnetohydrodynamics equations are essential to understanding the solar system's plasma phenomena, including the large-scale solar corona, the solar wind's interaction with planetary magnetospheres,(More)
The Space Weather Modeling Framework (SWMF) has been developed to provide NASA and the modeling community with a high-performance computational tool with " plug-and-play " capabilities to model the physics from the surface of the Sun to the upper atmosphere of the Earth. Its recently released working prototype includes five components for the following(More)
We present a parallel explicit/implicit time integration scheme well suited for block-adaptive grids. The basic idea of the algorithm is that the time stepping scheme can differ in the blocks of the grid for a given time step: an explicit scheme is used in the blocks where the local stability requirement is not violated and an implicit scheme is used in the(More)
