✦ Synopsis

A Cartesian adaptive mesh code for time-dependent, compressible hydrodynamics (HD) and idea1 magnetohydrodynamics (MHD) in three space dimensions has been developed. The strategy of multiple subgrid nesting is used for mesh refinement and is incorporated into an operator-split, mixed finite-difference/finite-volume scheme. Special emphasis is laid on a flexible mesh adjustment realized by rectangular blocks of 4 x 4 x 4 numerical cells. These blocks can recursively be nested and spatially arranged according to local resolution requirements. HD/MHD test calculations are performed to check code functionality and to estimate the efficiency of the applied mesh refinement philosophy.

A fully three-dimensional spectral code has been developed and implemented. It computes three-dimensional equilibria using the variational approach, by minimizing the potential energy subject to appropriate constraints. A second minimization, with an additional constraint, is used to examine the sta
