The HEC-RAS compute engine is, as its name suggests, the component that actually performs the HEC-RAS simulation. This simulation is controlled from the FEWS Adapter, and all run time data such as initial and boundary conditions, and parameter settings are passed through the adapter from and to the FEWS Forecasting Shell.
