Abstract
Model based development is increasingly used to minimise costly and time consuming testing of physical prototypes during product development. Modelling and concept evaluation by using computer models tor performance prediction will then be a substantial part of the PD process synthesis-analysis loop. However, easy-to-use and flexible methods have to be used for modelling, especially during product concept development, to avoid traditional coding and debugging. In this case, a twin-screw compressor has been modelled using the visual programming language MATLAB/Simulink. One of the objectives was to investigate whether it was feasible and appropriate to use MATLAB/Simulink for such a complex task. New developed methods have been used for this. The main difficulty turned out to be how to create a queue-like environment for the chambers. This problem was eventually solved, but it shows how MATLAB/Simulink can be cumbersome to use when dealing with complex problems.
