- Two variants of the advection upstream splitting method are modified to solve the equations of ideal
magnetohydrodynamics. Discontinuity-sensing functions used in AUSMPW and M-AUSMPW for the
magnetohydrodynamics equations are newly defined in consideration of a magnetic field. The new pressure-based
weight functions are shown to effectively remove the oscillations behind a strong shock wave as well as provide a
highly accurate solution for a stationary contact discontinuity. To satisfy the divergence-free constraint of a magnetic
field, the hyperbolic divergence cleaning method is chosen and applied for all the test cases. Ryu and Jones onedimensional
magnetohydrodynamics shock-tube problem and Orszag and Tangs two-dimensional magnetohydrodynamics
vortex system are evaluated to validate and show the advantages of the newly developed schemes.
