AZEuS: An Adaptive Zone Eulerian Scheme for Computational MHD | | Jon P. Ramsey

19 Dec 2011 | | Abstract: | A new adaptive mesh refinement (AMR) version of the ZEUS-3D astrophysical
magnetohydrodynamical (MHD) fluid code, AZEuS, is described. The AMR module in
AZEuS has been completely adapted to the staggered mesh that characterises the
ZEUS family of codes, on which scalar quantities are zone-centred and vector
components are face-centred. In addition, for applications using static grids,
it is necessary to use higher-order interpolations for prolongation to minimise
the errors caused by waves crossing from a grid of one resolution to another.
Finally, solutions to test problems in 1-, 2-, and 3-dimensions in both
Cartesian and spherical coordinates are presented. | | Source: | arXiv, 1112.4390 | | Services: | Forum | Review | PDF | Favorites | |
