Dassault Systemes has released Isight 5.6, the open desktop solution for simulation process automation and design optimisation from Simulia, the Dassault brand for realistic simulation.
According to Dassault, Isight 5.6 includes enhancements in optimisation, modelling and simulation integration, and post-processing. They explain that Isight provides designers, engineers and researchers with an open system for integrating design and simulation models, created with various CAD, CAE and other software applications, to automate the execution of hundreds or thousands of simulations. They say Isight allows users to save time and improve their products by optimising them against performance or cost metrics through statistical methods such as Design of Experiments (DOE) or Design for Six Sigma.
“Isight has features and add-ons that allow us to integrate all of the different codes and interfaces used for our physics subroutines,” said Cosimo Chiarelli, Head of the Aeromechanics and Propulsion unit in Business Segment Space Infrastructure and Transportation at Thales Alenia Space Italia in Turin. “It played a key role in helping us unify our processes and saved a considerable amount of time in our design optimisation process.”
Among the new features for design optimisation, Dassault say that Isight 5.6 provides a reliability analysis technique for importance sampling that allows users to compute and sample around the most probable point of failure in a design. When compared to sampling around the mean value point, importance sampling requires orders of magnitude fewer evaluations for the same accuracy in predicting the probability of failure or success. This is especially important in the verification of high-reliability systems, such as jet turbines or automotive brakes.
“Many customers, such as Thales Alenia Space, are gaining significant business benefits from using Isight as a tool for virtual product verification and validation,” said Alex Van der Velden, Director, Simulia, Dassault. “For example, when designing a space vehicle, one rarely has the luxury of using full-scale physical prototypes to iteratively optimise both the vehicle and its reentry trajectory. Virtual testing supported by simulation automation and design exploration technology is critical in helping manufacturing companies achieve the right performing design, faster and with less physical testing.”
Dassault claims that Isight 5.6 enhances several components, which are the building blocks of simulation process flows. They say it delivers a number of post-processing enhancements, including new options in the approximation viewer for overlay constraints graphs to perform quick trade-off studies by relaxing constraints, showing or hiding constraint boundaries, and viewing constraint violations using a floor projection graph.
