Function Documentation

int compute_interface_flux (  struct flow_state  Lft[], struct flow_state  Rght[], struct flux_data_1D  IF[], int  first, int  last )

Compute the inviscid fluxes (in 2D) across the cell interfaces. This is the top-level function that calls the previously selected flux calculator. Much of the detailed work is delegated. Parameters: Lft  : pointer to the array of LEFT flow states Rght  : pointer to the array of RIGHT flow states IF  : pointer to the array of interfaces where the fluxes are to be stored first  : index of the first interface to be used last  : index of the last interface

int compute_interface_flux_3D (  struct flow_state  Lft[], struct flow_state  Rght[], struct flux_data_1D  IFlux[], int  first, int  last )

Compute the inviscid fluxes (in 3D) across the cell interfaces. This is the top-level function that calls the previously selected flux calculator. Much of the detailed work is delegated. Parameters: Lft  : pointer to the array of LEFT flow states Rght  : pointer to the array of RIGHT flow states IF  : pointer to the array of interfaces where the fluxes are to be stored first  : index of the first interface to be used last  : index of the last interface Todo: Really don't require npq_mom and xyz_mom to be separately stored. Just keep xyz_mom (and rename to momentum).

int copy_gas_state (  struct flow_state *  from_gs, struct flow_state *  to_gs )

Copy the flow_state data (gas_data plus flow velocities.). Parameters: from_gs  : pointer to source data structure to_gs  : pointer to target data structure
