Why system simulation?

Any engineer, from small or corporate enterprises, can create and solve sophisticated design tasks and dynamic calculations with a clear modeling concept – without detailed knowledge in programming or the need to be skilled across all sorts of physical domains.

Virtual experiments with dynamic, nonlinear behavior of entire systems

Development tools which specialize only in one particular area often fail the manifold requirements in the field of mechatronics. This usually results in overdesigned systems, system failure as well as expensive and time-consuming revisions.

Wherever FEM and CFD analyses deliver accurate predictions about individual components and assemblies, dynamic system simulation examines time-dependent processes of the entire system. Such systems can also consist of components from different technical domains. The method of discrete networks combines the individual components (elements), which themselves can contain sub-components, through physical connections. This creates an abstract simulation model with varying complexity consisting of many elements and connections from various physical domains.


Advantages of simulating complex physical systems

Make principle decisions that are based on computed results – the sooner, the better. Advantages and benefits of virtual product development methods are obvious: simulation software helps you early on in your risk assessment and saves you time and money.

  • Examination and proof a machine’s operational safety:
    • Which loads lead to defects in what timeframe?
    • How does a system behave in extreme or disastrous situations?
    • How safe are new ideas and concepts?

  • Increased performance and efficiency:
    • Which parameter has what effect on the performance and efficiency of my system?
    • What impact does changing a particular parameter have on the system?
    • How does an alternative structure behave?

  • Decisions in the development process based on solid facts:
    • Which alterations have what effect on achieving my development targets (e.g. performance, safety, costs)?
    • Does my (machine) concept perform as expected?

Simulation as the gateway to reality

CAD engineers in many industries are still facing great challenges in ensuring certain technical properties, for example in drive systems or machinery in general. Linear design methods often have their limits as they can only be applied to linear system behavior – a constraint that real drive systems rarely meet. Moreover, they have to account for various interactions between different physical domains.

The boundaries of traditional development methods and the reasons for a combination of computer-aided simulation and engineering services are diverse:

  • Analyses of real systems or physical models are too expensive and/or time-consuming -> simulation saves time and money.
  • Health and safety must not be compromised -> damages to goods and replacement costs are to be avoided
  • A certain behavior of a system or of vital parts of it needs to be evaluated before they even exist
  • The exact effect of a particular change in the system cannot be tested for the real object or only with great difficulty as there are too many influencing factors involved.
