ITI Launches SimulationX 3.4

DRESDEN, Germany, November 30, 2010 - 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
, 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."
