Functions/Subroutines | |
| impure subroutine, public | s_initialize_derived_variables_module |
| Computation of parameters, allocation procedures, and/or any other tasks needed to properly setup the module. | |
| subroutine, public | s_derive_specific_heat_ratio (q_sf) |
| Derive the specific heat ratio from the specific heat ratio function gamma_sf. The latter is stored in the derived flow quantity storage variable, q_sf. | |
| subroutine, public | s_derive_liquid_stiffness (q_sf) |
| Compute the liquid stiffness from the specific heat ratio function gamma_sf and the liquid stiffness function pi_inf_sf, respectively. These are used to calculate the values of the liquid stiffness, which are stored in the derived flow quantity storage variable, q_sf. | |
| subroutine, public | s_derive_sound_speed (q_prim_vf, q_sf) |
| Compute the speed of sound from the primitive variables, density, specific heat ratio function, and liquid stiffness function. It then computes from those variables the values of the speed of sound, which are stored in the derived flow quantity storage variable, q_sf. | |
| subroutine, public | s_derive_flux_limiter (i, q_prim_vf, q_sf) |
| Derive the flux limiter at cell boundary i+1/2. This is an approximation because the velocity used to determine the upwind direction is the velocity at the cell center i instead of the contact velocity at the cell boundary from the Riemann solver. | |
| subroutine | s_solve_linear_system (a, b, sol, ndim) |
| Solve Ax=b via Gaussian elimination with partial pivoting. | |
| subroutine, public | s_derive_vorticity_component (i, q_prim_vf, q_sf) |
| Compute the specified component of the vorticity from the primitive variables. From those inputs, it proceeds to calculate values of the desired vorticity component, which are subsequently stored in derived flow quantity storage variable, q_sf. | |
| subroutine, public | s_derive_qm (q_prim_vf, q_sf) |
| Compute the Q_M criterion from the primitive variables. The Q_M function, which are subsequently stored in the derived flow quantity storage variable, q_sf. | |

| impure subroutine, public | s_derive_numerical_schlieren_function (q_cons_vf, q_sf) |
| Compute the values of the numerical Schlieren function, which are subsequently stored in the derived flow quantity storage variable, q_sf. | |
