Abstract
The target was to develop a coupling between simulation methods that allow the user to cover overall vehicle heat management analysis. An efficient analysis is only possible when interactions between subsystems of a vehicle are considered simultaneously. As simulation software is available for many subsystems, it is useful to combine them in a way that only less manual iteration steps have to be performed. The subdivision into 3 subsystems, the engine cooling circuit, the cooling air flow and the air conditioning circuit can be covered by efficient and accurate one-dimensional network simulation software tools. For detailed flow information 3-dimensional CFD tools can be brought in. To hand over simulation results from one software package to get boundary conditions for the other package is the first step. To exchange this information in both directions and to consider interdependencies between the subsystems is the second step. In the following typically applications of such software integration methods are shown.
