The latest release of Isight 5.6, an open desktop solution for simulation process automation and design optimization from SIMULIA, promises to accelerate design space exploration with smarter optimization and open integration enhancements. Added features for design optimization include a reliability analysis technique for importance sampling that allows users to compute and sample around the most probable point of failure in a design, updates to the Abaqus component 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, and improvements to the Data Matching component that enable the definition and matching of multiple data sets within multiple ranges. Post-processing enhancements include more 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.
