ITI software and engineering launch latest version of SimulationX physical modelling system

ITI, one of the leading software and engineering companies specializing in system simulation, is proud to announce its release of the latest version of SimulationX, the standard software for physical modelling of mechatronic systems. The new version is a user-oriented enhancement with numerous functional innovations and is now available in a 64-bit version for the first time. Besides having considerable library enhancements, SimulationX 3.4 also contains the new Torsional Vibration Analysis package with model objects tailored for simulations in the frequency domain. With new interfaces in multi-body mechanics and controls, improved CAD import and full support of Modelica 3.1, SimulationX from ITI is an essential tool for those working in the field of system simulation.

To meet the special requirements that exist regarding the evaluation and certification of drive systems, SimulationX 3.4 contains a new package called Torsional Vibration Analysis. This adds a comprehensive model library for sensitivity studies and efficient modelling for steady-state simulation of drive systems to the SimulationX solution portfolio. The linear and non-linear models in this package are perfectly tailored to the extensive steady-state simulation capabilities in SimulationX. Due to the open library structure, users are able to extend and modify this library in line with their own requirements regarding simulation and analysis.

In version 3.4, SimulationX now supports the import of CAD data from SolidWorks in addition to Pro/ENGINEER. Geometrical dependencies can be defined by an enhanced CAD component import for the very first time. Once this is done, the model elements created are automatically connected in accordance with the defined dependencies, the positions of the model elements in the structure view being taken from the positions in the CAD component. This enhanced manageability of the models results in a significant reduction in the manual effort required and the error rate on importing CAD models.

The new FEM Import Interface and the fully integrated ExpertControl tools ecCST and ecICP are further highlights of SimulationX 3.4. Using the FEM interface, three-dimensional mechanical structures from popular FE programs can easily be imported into a SimulationX multi-body system. At the same time, any elastic structure may be integrated as an order-reduced sub-model. Thus, large motions in a non-inertial reference frame are permissible and model comprehension is improved by the realistic visualization of the deforming FE mesh. Users are able to simulate dynamical models exhaustively with this tool. As for controls, the two ExpertControl tools ecCST and ecICP are at the engineer’s disposal to evaluate the best controllers in the early stages of product development. As a result, setting up controllers is now considerably simpler and faster.

On top of this, SimulationX 3.4 incorporates various new and innovative model elements in the libraries of power transmission, 1-D mechanics, multi-body systems, hydraulics, thermal fluidics and controls. These improve performance for real-time models and provide more convenient modelling for automotive, offshore, subsea and marine applications.

Thanks to its full support of Modelica 3.1, SimulationX 3.4 is easy for traditional Modelica users to work with and ensures considerably enhanced model handling as well as greater modelling efficiency. Moreover, new and improved interfaces are available for users of software tools such as MATLAB/Simulink, CarSim, modeFRONTIER, Ansys, Comsol, LabVIEW, NI VeriStand and FMI (Functional Mock-up Interface).

"Our vision is to make the physical processes taking place in technical plants more transparent and thus to simplify decisions," says Thomas Neidhold, Software Development Manager at ITI. "SimulationX is a tool that simplifies and speeds up the modelling process for customers due to a wide range of powerful new functions and enhancements."
