AMREX_GPU_HOST_DEVICE AMREX_INLINE void riemanncg (const RiemannState &ql, const RiemannState &qr, const RiemannAux &raux, RiemannState &qint)

The Colella-Glaz Riemann solver for pure hydrodynamics. This is a two shock approximate state Riemann solver.

Parameters:

  • bx – the box to operate over

  • ql – the left interface state

  • qr – the right interface state

  • qaux_arr – the auxiliary state

  • qint – the full Godunov state on the interface

  • idir – coordinate direction for the solve (0 = x, 1 = y, 2 = z)

AMREX_GPU_HOST_DEVICE AMREX_INLINE void riemannus (const RiemannState &ql, const RiemannState &qr, const RiemannAux &raux, RiemannState &qint)

Parameters:

  • bx – the box to operate over

  • ql – the left interface state

  • qr – the right interface state

  • qaux_arr – the auxiliary state

  • qint – the full Godunov state on the interface

  • lambda_int – the radiation flux limiter on the interface
