Megagauss magnetic fields and surface plasmas: Physical insight, computational issues

摘要

. In this paper we report Eulerian computations that show improved agreement with the observations. It is quite common to use computations that “match the experiment” to interpret the experimental results, and we report an interpretation based upon the Eulerian results. However, we have also compared the Eulerian computations with the Lagrangian calculations of Garanin and Lagrangian calculations performed with the computer code Raven. The comparisons between the codes give rise to serious concerns about the differences between Eulerian and Lagrangian simulations and about the differences between van der Waals and Maxwell-construct equations-of-state.
