Dassault Systèmes has released Isight 5.6, an open desktop solution for simulation process automation and design optimisation from Simulia, the company’s brand for realistic simulation. Isight 5.6 includes enhancements in optimisation, modelling and simulation integration, and post processing.

The software 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. It enables users to optimise their products against performance or cost metrics through statistical methods such as Design of Experiments (DOE) or Design for Six Sigma.

Among the new features for design optimisation is 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.

Updates to the Abaqus component have also been included to support multiple Abaqus/CAE cases by providing users with the option to parse all detected input files and create output parameters for multiple analyses. Improvements to the Data Matching component enable the definition and matching of multiple data sets within multiple ranges. In addition, post processing has been enhanced, 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.
