Since November 2010 SimulationX 3.4 is available - even as 64bit version for the first time. Besides numerous features and functions that simplify and accelerate the modeling process SimulationX fully supports Modelica 3.1.
New TVA Package for Simulation in Frequency Domain | With the new package Torsional Vibration Analysis SimulationX is enhanced with an efficient model library for steady-state simulation of drive systems with combustion engines, electrical machines, gears and typical loads. The package contains linear and non-linear models tailored to the extensive steady-state simulation capabilities in SimulationX and the special requirements in the evaluation and certification of drive systems. The open structure of the TVA package allows easy modification and enhancement by the user.
Enhanced CAD Import | In addition to Pro/ENGINEER SimulationX 3.4 now supports also SolidWorks. The enhanced CAD component import now allows the definition of geometrical dependencies. The created model elements are connected according to the defined dependencies, whereby the position of the model elements in the structure view is taken from the position in the CAD component. This enables enhanced management of the model results with significantly reduced manual effort and reduced potential for errors in the import of CAD models.
Enhanced Robustness and Performance for CVODE and Code Export | Thanks to optimized linear equation solvers and event handling, as well as the efficient Jacobian matrix computation the CVODE solver has been improved in robustness and speed. Especially variant computations with large models are accelerated considerably. Enhancements in the SimulationX Modelica Compiler and the consequent use of Common Sub Expressions allow the generation of more efficient C Code. This reduces the required computation time when using SimulationX models within real-time applications and in turn allows the implementation of more complex models.
Significant Speed-Up for Steady-State Simulation | The improved step-size control applied in the new „Linear Method with Interpolation” reduces computation time significantly. In typical applications, such as combustion engine drive trains in ship propulsion systems or construction equipment, simulation times are reduced by a factor 10.
Complete Range of the Modelica Language | SimulationX 3.4 delivers enhanced model handling and an easy introduction for traditional Modelica users due to the full support of Modelica 3.1. SimulationX greatly increases the efficiency of this standardized modeling language.
Accelerated and Simplified Modeling with Extensive Library Enhancements | This new release contains extensive modeling enhancements in the SimulationX libraries of power transmission, 1D mechanics, multi-body mechanics, hydraulics, thermo fluids, and controls. These enhancements improve amongst others the performance for real-time models and provide a more comfortable modeling environment for engineers in the field of automotive, offshore/subsea and marine.
SimulationX available as 64bit version
With the version 3.4 SimulationX will be available as 64bit Version. The user will benefit from a bigger memory area and therewith almost boundless modeling opportunities.
With this version the users will benefit from an enhanced utilization of the complete hardware resources having the opportunity to tap the potential of its operating system. With more than 4 GB of RAM this version perfectly supports larger models and therewith provides a higher simulation performance and accuracy under certain conditions. Furthermore with the 64bit version the graphical user interface of SimulationX seems to touch more fluently.
For any further information on the 64bit version of SimulationX please contact the ITI team at 64bit@simulationx.com.
New Interfaces Improve Flexibility
Import of Three-Dimensional Mechanical Structures | The new SimulationX FEM Import Interface imports three-dimensional mechanical structures from popular FE programs like ANSYS, COMSOL Multiphysics or MSC.Nastran into the SimulationX MBS Mechanics library. Any elastic structure (beam, shell, solid etc.) may be integrated as order-reduced sub model and thus used within the context of system simulation. Compared to the existing “Modal system” import from ANSYS, large motion of the imported elastic body in a non-inertial reference frame is permissible. Furthermore, the model comprehension is improved by the realistic visualization of the deforming FE mesh.
Integration of Partner Tool Revolutionizes Control Design | The ExpertControl design tools ecCST and ecICP are now fully integrated into SimulationX 3.4. They provide the engineer with fully automatic design capabilities for optimum controllers in early product development stages. As a result, the identification of transfer functions and the set-up of controllers are considerably simplified and accelerated.
Platform-Independent Model Exchange | SimulationX 3.4 supports the creation and import of Modelisar Functional MockUp Units (FMU). Standardized interfaces facilitate the platform-independent exchange of simulation models and increase the flexibility in the connection of external simulation tools and models, which implement an equation-based interface (FMI for Model Exchange) or contain an embedded solver (FMI for Co-Simulation).
New Target Platforms for Real-time Applications | The Code-Export to Simulink now can integrate the Fixed-Step Solver into the generated S-Function. This has advantages when transferring the models to real-time platforms by means of the Real-Time Workshop®, permitting oversampling as well as the integration into triggered-, function call-, or enabled subsystems. SCALE-RT 5.1 by Cosateq is now supported as new target platform.
