Parameters:

  • loc – spatial location

  • linear_mom – linear momentum

  • hybrid_mom – hybrid / angular momentum

AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE void hybrid_to_linear (const GpuArray< Real, 3 > &loc, const GpuArray< Real, 3 > &hybrid_mom, GpuArray< Real, 3 > &linear_mom)

Convert the hybrid / angular momentum back to linear momentum

Parameters:

  • loc – spatial location

  • hybrid_mom – hybrid / angular momentum

  • linear_mom – linear momentum

AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE void set_hybrid_momentum_source (const GpuArray< Real, 3 > &loc, const GpuArray< Real, 3 > &linear_source, GpuArray< Real, 3 > &hybrid_source)

Create the hydrodynamic source term for the hybrid momenta based on the input linear momentum source term

Parameters:

  • loc – spatial location

  • linear_source – linear momentum source term

AMREX_GPU_HOST_DEVICE AMREX_FORCE_INLINE void compute_hybrid_flux (const GpuArray< Real, NGDNV > &state, const GeometryData &geomdata, int idir, int i, int j, int k, GpuArray< Real, NUM_STATE > &flux, bool cell_centered=false)

Compute and store the flux of the hybrid momentum components

Parameters:

  • state – the Godunov state

  • geomdata – the Castro geometry data object

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

  • i – x zone index

  • j – y zone index

  • k – z zone indxe

  • flux – hydrodynamic flux in direction idir

  • cell_centered – is this a cell-centered flux or an interface flux?
