RSYST - FROM NUCLEAR-REACTOR CALCULATIONS TOWARDS A HIGHLY SOPHISTICATED SCIENTIFIC SOFTWARE INTEGRATION ENVIRONMENT

The software environment RSYST was originally used to solve problems o f reactor physics. The consideration of advanced scientific simulation requirements and the strict application of modern software design pri nciples led to a system which is perfectly suitable to solve problems in various complex scientific problem domains. Starting with a review of the early days of RSYST, we describe the straight evolution driven by the need of software environment which combines the advantages of a high-performance database system with the capability to integrate sop histicated scientific technical applications. The RSYST architecture i s presented and the data modelling capabilities are described. To demo nstrate the powerful possibilities and flexibility of the RSYST enviro nment, we describe a wide range of RSYST applications, e.g., mechanica l simulations of multibody systems which are used in biomechanical res earch, civil engineering and robotics. In addition, a hypermedia syste m which is used for scientific technical training and documentation is presented.
