pSeven 6.1 Release

DATADVANCE development team is pleased to announce the release of pSeven 6.1, a new stable version of our data analysis and design space exploration platform.

This release features a major update of the Siemens NX integration block, std.NX starting with the added support for Siemens NX 10. std.NX now also supports Unicode in file names, paths, names of model features and dimensions, and can parse expressions defined in the working model, so they are added to block configuration and can be changed from a pSeven workflow.

Various smaller updates and fixes have been applied to other integration blocks, including both the direct integration components (std.Creo, std.SolidWorks) and general purpose integration blocks (std.ShellScript, std.Text).

pSeven 6.1 has also received the following updates from MACROS 6.1 which is included in this release:

  • Solving mixed-integer optimization problems no longer requires using the surrogate based optimization (SBO) method, simplifying configuration of such problems.
  • Further improvement in dealing with cusp-like singularities in optimization problems thanks to the update of gradient-based optimization methods started in MACROS 6.0.
  • New sparse linear regression approximation technique. This method is based on elastic net regularization and is available as an option when using the RSM technique.

The last but not the least, a recent review of the pSeven's database mechanism allowed to add the capability to compact project databases. Compacting cleans redundant data records that were previously kept for safety reasons and can notably reduce database size if it was actively used. Note that since the process can be time consuming, databases are never compacted automatically; it is a manual command available from the database menu.

pSeven 6.1 also includes numerous stability improvements and other minor bugfixes. For a detailed list of updates, please see the release changelog. You can also contact us to receive more information and pSeven updates!
