The advective upstream splitting method (AUSM) developed for fluid dynamicsproblems has been applied to solving hydrodynamic semiconductor equations coupledwith the Poisson’s equation. In the AUSM, the flux vectors of a fluid system are splitinto a convective component and a diffusive pressure component. Discretization of thesetwo physically distinct fluxes is thus performed separately in AUSM. Application of thedeveloped hydrodynamic AUSM to a GaAs MESFET with a gate length of 0.1 μm hasdemonstrated its simplicity, efficiency and effectiveness in dealing with the highlynonlinear hydrodynamic device system
