Multidisciplinary simulations become increasingly important to meet the growing demands on the quality of simulation results. Our software MpCCI is the world's leading tool for multiphysics simulations, which require a combination of proven application codes for individual disciplines (flow, structure, acoustics, heat etc.).
The possibilities of use of MpCCI are manifold and relate to very different fields of application.
Concerning the thermal behavior of automotive vehicles it is pursued to accomplish simulations for the full complexity of a vehicle's geometry and transport phenomena of heat including convection, radiation and conduction in fluids and solid bodies. The different heat transport mechanisms described are solved by specialized codes. The coupled approach supports steady state, transient and mixed type (quasi-stationary with transient) applications.
Multi-body simulation (MBS) and finite element methods (FEM) are effective tools to calculate the complex dynamics of vehicles and machine parts. Co-simulation is a natural means to increase the accuracy of such models. Co-simulation also allows to take into account external influences on the vehicle or additional physical phenomena such as flow or electromagnetic phenomena. Application examples are driving over obstacles, driving through waters or the interaction of an excavator with the ground.
When it comes to engine development, one particularly critical component is the exhaust gas turbocharger, due mostly to the loads of extremely high turbine speeds and high exhaust temperatures. As components become smaller, manufacturing tolerances and the slightest modification of component geometry during operation – due, say, to interactions between exhaust flow and turbine blades – play an ever-greater role.
Bei der Entwicklung immer effizienterer Turbomaschinen müssen mechanische, thermodynamische und strömungsmechanische Vorgänge berücksichtigt werden, um Strömungsgeometrie, thermodynamische Belastungen oder Lebensdauer zu optimieren.
Fluid structure simulations are used in the automotive field in various applications, for example in the development of new axial hydraulic pumps or in the optimization of spoilers of racing vehicles.
