A new version of ETA’s mechanical engineering simulation software, the Inventium Suite 2018 R2, which includes PreSys for finite element modeling and NISA for finite element analysis (FEA), was released with many new and enhanced features.
The Inventium Suite includes some progressive new tools, while retaining ETA’s legacy software products VPG and DYNAFORM. Inventium’s unified and streamlined product architecture provides users access to all of the suite’s software tools. By design, Inventium products offer a high performance modeling and post-processing system, while providing a robust path for the integration of new tools and third party applications.
The Inventium architecture was developed with flexibility and configurability in mind. It allows the user to change the way their software appears and behaves. New Menus or Toolbars may be created to meet the user’s specific needs, while pre-configured menus can be modified as desired. For example, if the user is not creating models which use solid elements, he or she may deactivate all functions relating to that type of task in the user toolbars and menus to simplify the interface. Similarly, the user can create a customized toolbar containing ‘favorites’, or frequently accessed functions.
