MACH2: A two-dimensional magnetohydrodynamic simulation code for complex experimental configurations

摘要: Abstract : MACH2 is a flexible and powerful two-dimensional magnetohydrodynamic simulation code designed specifically to handle complex experimental configurations. The code's capabilities include numerically generated solution-adaptive grid which permits it be used for either Eulerian or Lagrangian flow problems, use of real equations state transport properties from the Los Alamos National Laboratory SESAME package, multigrid implicit magnetic field diffusion solver can simulate problems with vacuum. descriptive power namelist-based problem input language sufficient that no modifications are required set up any broad class problems. Almost knowledge internal data structures numerical techniques do simulations realistically model experiments. This made possible by multiblock architecture table-driven control structure. Code reliability flexibility ensured enhanced structured modular implementation boundary conditions block coupling. report details physical model, including conditions; permissible geometries; time differencing; spatial discretization, centering, differencing MACH2.
