Leveraging pSeven 3.0 new capabilities facilitates collaboration, enhances surrogate modeling and accelerates optimization

Nafems Industry News- Datadvance pSeven 3.0Multiple improvements and new capabilities incorporated in pSeven 3.0 deliver enhanced collaboration of product development team and significantly simplify the routine engineering tasks. Innovative Generic Tool for Sensitivity and Dependency Analysis introduced in the newest release of MACROS — pSeven’s algorithmic core — is aimed to create value by reducing up to 6 times the computational time in certain cases of optimization and enhance the accuracy of surrogate modelling.


Easier collaboration, less routine

In the course of a typical product development process, design team is required to perform multiple iterations with the model and CAE data, changing only critical parameters while others can be kept unmodified. Powerful CAD/CAE tools integration capabilities of pSeven are enhanced with the new methodology named Workflow as a Ready Tool. It enables the methods and tools department to deliver efficient engineering processes/workflows and ensure these validated workflows are used as ready tools by the product design team. The design team user can apply changes to inputs and parameters without editing the workflow. Moreover, workflow designer can prepare instructions for users, adding useful comments directly into the workflow and giving descriptive names to workflow inputs, outputs and parameters to help users understand the configuration and accelerate design team work.

Product development flexibility is greatly enhanced with the new capabilities of reusing existing workflows as a component of a new workflow and other multiple improvements of data input, handling and editing.

CAD interoperability is taken to a higher level of efficiency in pSeven 3.0 with the new SolidWorks integration block. It now ensures the full support of SolidWorks assemblies, global variables and unit specifications, as well as an easy connection of document parameters with block variables. This eliminates manual setting of all the parameters in pSeven block, allows instant actions and significantly improves user experience. Coupled with the automatic parallel execution of composite blocks and the reuse capabilities stated above, these features tremendously accelerate calculations.


New Sensitivity and Dependency Analysis tool for faster and more accurate surrogate modelling, optimization and design of experiments

The Generic Tool for Sensitivity and Dependency Analysis (GT SDA), introduced in MACROS 3.0 release, addresses the issues present in virtually every surrogate modeling or optimization process — high time/memory requirements and the need to efficiently spend the model calls budget. The fully automated techniques of this extremely easy to use and powerful tool add intelligence and speed into the processes of filtering non-informative features (design parameters) in the study, ranking the informative ones with respect to their influence on the given response function, and selecting features that provide the best approximation. Information provided by the GT SDA is extremely beneficial, delivering highly accurate approximations to replace time-consuming computations and providing in certain cases up to 6 times reduction of function calls during the optimization.
Many other enhancements and expanded capabilities of pSeven and MACROS technology are available in pSeven 3.0 Release notes and MACROS 3.0 release notes.
