TUTSIM was the first commercial simulation software ever to run on an IBM-PC. The package was used for the modeling and simulation of multi-domain systems using differential equations and bond graphs.
TUTSIM (Twente University of Technology SIMulator) was developed at the Control Laboratory of the University of Twente in the early 70's. The program was initially created for the PDP-11 and LSI-11 series of DEC. At the end of the 70's it was ported to run on microprocessors like the MOS Technology 6502 of the Apple II and the Intel 8086 of the IBM Personal Computer.
The company Meerman Automation took over the development of the package in the early 80's. The rise of the IBM PC gave TUTSIM its world fame, making scientific simulation software available for researchers all over the world. Failing to meet the demands of a graphical user interface with the rise of Microsoft Windows in the late 80's the popularity of TUTSIM slowly faded away. Multiple requests from bond graph researchers caused the University of Twente to begin development of a successor to TUTSIM. This resulted in the software 20-sim, released by Controllab, which contained many of the features that made TUTSIM popular.
