摘要：

An approximate Riemann solver of Godunov type for ideal relativistic magnetohydrodynamic equations (RMHD) named as HLLC ("C" denotes contact) is developed. In HLLC the Riernann fan is approximated by two intermediate states, which are separated by the entropy wave. Numerical tests show that HLLC resolves contact discontinuity more accurately than the Harten-Lax-van Leer (HLL) method and an isolated contact discontinuity exactly. (C) 2006 Elsevier Inc.
