| Dispatch to the subroutines that are utilized to compute the viscous source fluxes for either Cartesian or cylindrical geometries. For more information please refer to: 1) s_compute_cartesian_viscous_source_flux 2) s_compute_cylindrical_viscous_source_flux. | |
| subroutine | s_populate_riemann_states_variables_buffers (ql_prim_rsx_vf, dql_prim_dx_vf, dql_prim_dy_vf, dql_prim_dz_vf, qr_prim_rsx_vf, dqr_prim_dx_vf, dqr_prim_dy_vf, dqr_prim_dz_vf, norm_dir, ix, iy, iz) |
| Populate the left and right Riemann state variable buffers based on boundary conditions. | |
| subroutine | s_initialize_riemann_solver (flux_src_vf, norm_dir) |
| Set up the chosen Riemann solver algorithm for the current direction. | |
| subroutine | s_compute_cylindrical_viscous_source_flux (vell_vf, dvell_dx_vf, dvell_dy_vf, dvell_dz_vf, velr_vf, dvelr_dx_vf, dvelr_dy_vf, dvelr_dz_vf, flux_src_vf, q_prim_vf, norm_dir, ix, iy, iz) |
| Compute cylindrical viscous source flux contributions for momentum and energy. | |
| subroutine | s_compute_cartesian_viscous_source_flux (dvell_dx_vf, dvell_dy_vf, dvell_dz_vf, dvelr_dx_vf, dvelr_dy_vf, dvelr_dz_vf, flux_src_vf, q_prim_vf, norm_dir) |
| Compute Cartesian viscous source flux contributions for momentum and energy. | |
| subroutine | s_calculate_shear_stress_tensor (vel_grad_avg, re_shear, divergence_v, tau_shear_out) |
| Compute shear stress tensor components. | |
| subroutine | s_calculate_bulk_stress_tensor (re_bulk, divergence_v, tau_bulk_out) |
| Compute bulk stress tensor components (diagonal only). | |
| subroutine | s_accumulate_mixture_properties (nf, alpha_rho_k, alpha_k, rho_k, gamma_k, pi_inf_k, qv_k) |
| Accumulate the mixture density, specific heat ratio function, liquid stiffness function, and internal energy reference of one Riemann state from its partial densities and volume fractions. The number of fluids is an explicit argument because the 5-equation bubble model accumulates over num_fluids - 1 fluids. | |
| subroutine | s_compute_interface_reynolds (alpha_k, re_k, re_size_loc1, re_size_loc2) |
| Compute the shear and volume Reynolds numbers of one Riemann state by inverse-weighting the fluid Reynolds numbers with the volume fractions. | |
| subroutine | s_compute_hypoelastic_interface_energy (nf, alpha_l, alpha_r, damage_l, damage_r, tau_e_l, tau_e_r, g_l, g_r, e_l, e_r) |
| Accumulate the hypoelastic stress contribution to the energies of the left and right Riemann states: mix the shear modulus over the fluids, scale it by the continuum damage state when damage is modeled, and add the elastic energy of each stress component (doubled for the shear components) on each side whose mixture modulus is non-negligible. The elastic shear stresses are loaded from the state buffers by the caller, which reuses them for the stress fluxes and elastic wave speeds. The G > verysmall per-side gate is a deliberate maintainer ruling that replaces HLL's former hard-coded G > 1000 stability floor, retiring its "TODO take out if statement if stable without". | |

| Compute the advective part of the HLLC star-state momentum flux in the wave-normal direction (pressure excluded), used to assemble the geometrical source flux of the cylindrical and azimuthal sweeps. | |
| subroutine | s_finalize_riemann_solver (flux_vf, flux_src_vf, flux_gsrc_vf, norm_dir) |
| Reshape and copy the Riemann-solver flux buffers back to the physical-space output arrays for the selected sweep direction, finalizing the Riemann solve. Two variants are emitted from one template so the shared unpermute logic cannot drift apart: the plain routine also copies the advection flux_src set and the grid_geometry==3 z-sweep geometric source flux, while the _hatR variant unpermutes the hat_R-anchored flux_hatR_rs* set of the fused dual-pass HLLD solve (called between the two RHS assemblies) and is a strict subset: flux_src is anchor-independent (already finalized with the hat_L set) and its geometric source flux only exists for the axisymmetric y-sweep. | |
