CONCLUSION
− Modeling with modular blocks (external subassemblies) offers exchanging components with complete data sets and modeling.
− The Projecteditor with the central document „Variantenliste“ enables an easy documentation and handling of multiple simulations without oversight. Furthermore it produces recognible format of results for

oversight. Furthermore it produces recognible format of results for internal and external use
− Automation based on standardized models and data increases speed and quality which is key requirement to use the full potential of 1D Simulation for the development of cooling systems
