TI, Dresden, Germany, recently released its latest version of SimulationX software. SimulationX 3.4 models system components from many different domains and allows mutual interaction and feedback on one platform. This distinguishes SimulationX from other CAE software, such as FEM, and CFD. It conducts modelling, simulation, and analysis of physical effects, with ready-to-use model libraries for hydraulics, pneumatics, power transmission, 1-D mechanics, 3-D multi-body systems, thermal fluidics, electrics and electrical drives, and controls. Simulation X 3.4 offers full support of Modelica 3.1, and interfaces are available for MatLab/Simulink, CarSim, mode-Frontier, Ansys, Comsol, LabView, NI VeriStand, and FMI.
SimulationX 3.4 is available in a 64-bit version that also contains a new torsional vibration analysis package with model objects tailored for simulations in the frequency domain. Torsional vibration analysis adds a comprehensive model library for sensitivity studies and efficient modelling for steady-state simulation of drive systems. Linear and nonlinear models in the package are tailored to the software’s extensive steady-state simulation capabilities. Users can modify and extend its open-structured library to their own requirements.
SimulationX 3.4 also supports importing of CAD data from SolidWorks and Pro/Engineer. Geometrical dependencies can be defined by an enhanced CAD component import, allowing model elements to automatically be connected in accordance with the defined dependencies. Positions of model elements in the structure view are taken from positions in the CAD component, significantly reducing the manual effort required and the error rate on importing CAD models.
An interface allows 3-D mechanical structures from FE programs to be imported into a SimulationX multi-body system. Any elastic structure also may be integrated as an order-reduced sub-model. This allows large motions in a non-inertial reference frame, and model comprehension is improved by the realistic visualization of the deforming FE mesh.
