20-sim supports component based modelling. This is a modelling technique for physical systems that uses ports to connect components. Ports transfer energy from one component to the other and back. This allows us to create models by coupling individual components. We can for example connect a mass component to a spring damper component. The simulation will then show the emerging behaviour in the form of resonance. Port based model also allows us to verify that energy is conserved. With ports you therefore focus on the physics of a machine and this will result in simulation models that will mimic a real machine very well.

Real-Time Physics

Our digital twins are simulation models that run in real-time. This means that when a simulation is carried out, it advances with actual time and can exchange data with external components such as 3D animations or PLCs. Running in real-time is crucial when humans are in the loop or when models are coupled to PLCs. We have extensive expertise creating physics-accurate models capable of running in real-time. To achieve this, we use special order reduction methods.

Validated Components

Controllab has developed simulation models for over 30 years. During this period, we have performed measurements on many machines and components. We have used these measurements to verify our simulation models. Now, we have a large library of validated physics-based machine component models. We use these models to build digital twins that accurately mimic real machines and run in real-time.
