The latest version of Parasolid software from Siemens Digital Industries Software (www.sw.siemens.com) includes enhancements to Convergent Modelling technology; this can now operate on models containing a mix of facet B-rep surfaces and classic B-rep surfaces, helping to support more-efficient workflows in a wide range of applications.

For example, in generative design — where new products are autonomously developed to satisfy design constraints — Convergent Modelling can restore ‘precise classic mating surfaces’ to a model that has undergone facet-based topology optimisation.

In reverse engineering processes, the new technology can be used to add precise analytic surfaces to scanned data of parts for re-manufacture.

The Parasolid geometric modelling kernel is used in Siemens’ own Solid Edge software and NX software, and it is at the core of the Xcelerator portfolio’s ‘open and flexible ecosystem’.

Parasolid is also used by over 350 other products, including many world-leading CAD, CAM, CAE and AEC software applications.
