Cosimulation for Thermal Management and Vehicle Dynamics Applications

From 2012 Automotive Simulation World Congress: MpCCI provides a vendor-independent software interface for cosimulation, and this presentation discusses recent automotive applications: thermal behavior including convection, radiation and conduction in fluids and solid bodies. A coupled MBS-FEA-simulation approach is presented. One example is passing a road hole by the left front wheel. The corresponding tire is modeled with the FEA approach. The position as boundary condition is provided by the multibody model in MSC Adams. Both programs simulate in parallel and communicate through MpCCI. Another example outlines the benefits of coupling 1-D system codes with full 3-D CFD codes like ANSYS Fluent for HVAC circuits with detailed models of passenger cabins to get a more realistic feeling for the thermal comfort.
