The use of modern technologies in the development of simulation software

For modelling purposes, complex technical processes are frequently broken down into elementary sub-processes, which are subsequently simulated with different programs and methods. This can only be done effectively if the individual programs are linked in terms of their contents. In order to create programs and program systems in such a way as to meet these requirements, processes are being analyzed and formalized at the IKV using the very latest computer science methods. The data models developed in this project will permit a program to be structured on a modular basis. Existing simulations are being seamlessly integrated into the structures being developed at the analyses stage. The structure of MOREX, the newly designed simulation program for the design of twin-screw extruders, was developed from these data models and is described here by way of an example. The program can easily be extended, and any missing functions can be integrated from existing modules.
