All the time, numerical simulation was our passion

2016

sonar-3D reached a quality, stability and performance to simulate complex models with up to 100’000 objects.

2009

In 2009 the development of our new 3D-simulation software sonar-3D made it feasable to simulate a copper or steel cable with a resolution down to the wire level or a yarn with all its fibres.

1998

A few years later, it was already possible to realistically simulate a mechanism with the complexity of a complete mechanical watch with the SILUX software. In this simulation, even the physical simulation of the individual interacting cogs was calculated in detail. The illustration shows part of a model of a “Reverso” watch made by Jaeger-LeCoultre.

1994

The continual physical simulation of a simple watch mechanism proved that a general, technical simulation program for a multi-body dynamic system was fundamentally possible. This eventually led to the development of SILUX software and its successor sonar-2D.

The animation shows an old simulation with the ALIEN program. It was presented at the 8th Symposium on Detonation in Albuquerque, New Mexico, USA. The simulation shows the initiation of the main charge of a 35 mm air-defence shell through a booster charge. At the time, the simulation required 8 days CPU calculation time on a VAX 11-780 computer. Today, this problem can be solved on a standard personal computer in a fraction of an hour. Today ALIEN is integrated in sonar-2D software.
