The model set-up is an easy starting point for those new to SIMPACK and, at the same time, offers complete control to advanced users.

Extensive modeling libraries support the user to rapidly create a model. Any type of joint, marker or force element (standard or user-defined), can be easily incorporated within the model. Use of a mouse enables the user to work interactively with the 3D representation. This not only saves time in setting up and modifying models but also reduces modeling errors.

The 3D graphical representation of a model can, as well as being completely set up within SIMPACK, created within CAD packages and then imported into SIMPACK.

3D animations of the results can also be easily created. Any multi-body model, once created within SIMPACK, can be exported as FORTRAN or C code. This allows SIMPACK models to be used in other simulation environments, making SIMPACK models ideal for hardware-in-the-loop and real-time applications.

Once the multi-body model has been set-up, the solver automatically creates the equations of motion.

The equations of motion set up by the SIMPACK solver are based upon unique algorithms. When the number of the degrees of freedom of a multi-body model increases, calculation effort increases only linearly rather then following a quadratic or even a cubic function.

This and the high performance integration methods enable SIMPACK to minimise calculation times, which has been demonstrated in countless benchmark tests. Carefully chosen default parameters guarantee secure and efficient integration of almost any model.

Additionally SIMPACK gives access to a large number of parameters allowing experienced users to tune the solver for complex systems.

Another key quality of the SIMPACK solver is the reliability and stability. Even challenging contact problems showing strong non-linearity, e.g. wheels losing and regaining contact can be easily solved.

Apart from the time integration, the SIMPACK solver also comprises of calculation methods for static equilibria, used to automatically determine pre-load forces for a given model state. The standard solver can also be used to perform an eigen value analysis, as well as for additional frequency domain calculation methods found in the SIMPACK NVH.

The 3D model may be easily animated within SIMPACK by using the results of a frequency analysis or integration run. Specific aspects of the animation may be readily investigated using fixed and moved cameras. Furthermore SIMPACK can generate films of the animations, which are often necessary for presentations.

A significant amount of time in detecting modelling errors may be saved with the help of SIMPACK's animations.

In addition to using animations, for investigating dynamic or kinematic behaviour, a user may also plot or export (e.g. ascii to excel) all corresponding numerical data.

Whether working within the time domain or frequency domain, SIMPACK's plot templates, along with curve import and overlay capability, enables fast and comprehensive data comparisons. (Re-running integrations are not necessary in SIMPACK when adding additional sensors to a model).

Plot data may be further analysed by using SIMPACK's extensive library of filters and curve superimposition features.
