program __m_cbc_fpp_f90__

The module features a large database of characteristic boundary conditions (CBC) for the Euler system of equations. This system is augmented by the appropriate advection equations utilized to capture the material interfaces. The closure is achieved by the stiffened equation of state and mixture relations. At this time, the following CBC are available: 1) Slip Wall 2) Nonreflecting Subsonic Buffer 3) Nonreflecting Subsonic Inflow 4) Nonreflecting Subsonic Outflow 5) Force-Free Subsonic Outflow 6) Constant Pressure Subsonic Outflow 7) Supersonic Inflow 8) Supersonic Outflow Please refer to Thompson (1987, 1990) for detailed descriptions.
