Modules

The major SimulationX modules at a glance

SimulationX for experts offers various modules which you can combine as you see fit – depending on your industry sector you work in and the development tasks at hand. The so-called Basic Module is the foundation for all SimulationX modules. It comes with various functionalities for modeling, simulating, analyzing and optimizing 1D mechanical systems fast and intuitively.

The SimulationX Basic Module includes functionalities for

  • Mechanics 1D
  • Control engineering
  • Animations
  • Analyses of eigenfrequencies and mode shapes
  • FMU import
  • Automation, exchange of data and models
  • Creation, organization and version management of model elements
  • Transient simulation in the time domain
  • Parameter studies
  • Performance analysis
  • Coupling with MS Office®

The Acoustics module is intended for modeling complex acoustic networks (1D), such as loudspeakers, in-ear headphones and microphones, but also mufflers and home appliances, such as vacuum cleaners and washing machines. Fluidic systems consisting of volumes, tubes or hole-shaped connections can be described and analyzed with respect to their acoustic properties. The provided model elements allow for comprehensive yet easy parameterization and can be combined with mechanical and electrical elements from other SimulationX libraries. 

The SimulationX module comprises the library

  • 1D Acoustics with acoustic admittance two-port

Also nonlinear effects on the acoustic behavior, such as magnetization curves or mechanical stops, can be modeled for mechanical, electrical or magnetic components. Harmonics caused by nonlinearities can be examined both in the time and frequency domains. For the analysis of acoustic properties, SimulationX offers various options for amplitude and phase responses, poles and zeroes of complex transfer functions, as well as Nyquist diagrams.

The model libraries and elements from the Power Transmission module help you model and analyze mechanical powertrains efficiently and speed up the simulation-based design process for controlled drive systems. You can parameterize your models with catalogue data and design parameters. In conjunction with animation bodies, you are able to create dynamic three-dimensional visualizations with ease.

  • Power Transmission 1D
  • Combustion Engines
  • Consumption Calculation
  • Synchronizers
  • Torsional Vibration Analysis

The libraries included in the module “Automotive Pneumatics” provide a broad range of pre-configured model elements for pneumatic braking and suspension systems. They are optimized for simulations of such systems as they are used in commercial vehicles, but are also suitable for simulations of passenger cars and rolling stock.

The SimulationX module comprises libraries for

  • Automotive pneumatics
  • Thermal

The libraries of the Mechanics module enable you to conduct efficient dynamic analyses of mechanical systems. Models are made up of elements for masses, inertias, spring-dampers and forces with physical parameters. The network-oriented modeling approach  that is typical of SimulationX accounts for your engineering view on mechanical systems and offers you intuitive and fast access to modeling. The module “Mechanics” is the basis for modeling drive technologies. In combination with the modules “Hydraulics” and “Pneumatics”, you can easily simulate entire fluid power systems with mechanical assemblies.

  • Mechanics 2D
  • 2D contacts
  • Chain and belt drives
  • Linkages

The libraries and elements of the module “Electrical Engineering” lets you model and simulate electrical and magnetic phenomena through corresponding network models. Detailed models of electric motors, step motors and converters form connections with the libraries of other domains, such as power transmission, control engineering, fluid power and mechanics, for comprehensive simulations of complex systems. The interface with the FEM software application JMAG-RT allows you to integrate detailed models of electromechanical components – with parameters from CAD data – into your SimulationX model.

  • Electric motors
  • Electromagnetic model elements with interface for JMAG-RT
  • Electronics and magnetics

The libraries in this module permit simulations of processes in heating and cooling systems, air conditioning systems and heat engines, but also of thermal phenomena in other applications, such as thermal behavior of powertrain components. Create your own device-specific models in line with your hydraulic and pneumatic diagrams with ready-to-use elements, such as cylinders, valves, pipes, pumps and tanks.

  • Hydraulics
  • Pneumatics

Also external nonlinearities like pressure and temperature dependent fluid properties, nonlinear valve properties, temperature changes, absorption and dispersion of gasses, as well as volumetric and mechanic energy conversion efficiency can be taken into account.

If you want to analyze two-phase behavior of fluids and gasses, you combine the fluid power libraries with the thermal-fluid ones. The libraries in this module can be flexibly coupled with SimulationX models from the modules “Mechanics”, “Power Transmission” and “Control Engineering” as well as the Modelica libraries from third parties.

  • Thermal
  • Thermal-fluid power
  • Heat exchangers
  • Energy technology

The libraries from the MBS Mechanics module help you model three-dimensional multibody systems (MBS) with open and closed chains. By importing CAD files, you can integrate models of any complexity.

The module is suited for analyses of wind turbines, modeling vehicle powertrains and chassis or for the examination of processing machinery, for instance.

The SimulationX module comprises libraries for

  • Multibody mechanics
  • CAD import
  • Beam elements
  • MBS power transmission

Functionalities for code export and model import as well as standardized interfaces ensure a convenient exchange of parameters, result variables, model structures and images with other CAx software programs, such as CAD, CAM, CAE, CAO, FEA/FEM, CFD or MBS.
