Numerical Boundary Conditions for Solar Magnetic Hydrodynamic Flows Using the Method of Characteristics

  • S. T. Wu (a1), A. H. Wang (a1) and W. P. Guo (a1)

Abstract

We discuss the self-consistent time-dependent numerical boundary conditions on the basis of theory of characteristics for magnetohydrodynamics (MHD) simulations of solar plasma flows. The importance of using self-consistent boundary conditions is demonstrated by using an example of modeling coronal dynamic structures. This example demonstrates that the self-consistent boundary conditions assure the correctness of the numerical solutions. Otherwise, erroneous numerical solutions will appear.
