Engineering Technology Associates, Inc. (ETA) is pleased to announce the availability of Version 5.8.1, of its complete die system simulation solution, DYNAFORM ™.  This latest release promises to deliver a robust environment for engineers to simulate and analyze the entire die system.  The FEA software solution guides the engineer through a wide range of stages in the manufacturing process, from cost estimation and die face design to formability analysis and stamping process simulation.

Some of the most significant enhancements in this version are delivered through DYNAFORM’s Die Face Engineering (DFE) module.  DFE now offers the capacity to parametrically build die faces for a symmetrical part.  Therefore, after the user defines the symmetry line, the program can automatically build the die faces for the other half of the symmetrical part accordingly.

Also notable, a ‘new product change replacement’ feature was added in 5.8.1.  It allows the user to retain the current die face design and simply drop in new product design surfaces, saving the user a great deal of time while providing greater flexibility.

Finally, a new ‘Auto Mesh’ option was added in DFE and allows the user to automatically mesh the CAD model immediately after it has been imported.

The Blank Size Engineering (BSE) module was also enhanced in the latest round of development.  The module was significantly improved upon by way of a streamlined guided user interface (GUI).  New dialogues within the GUI contain tabbed menus for easy navigation between functions.

PreSys™ R3 Release

Written by

Engineering Technology Associates, Inc. (ETA) is pleased to announce the availability of the latest version of their advanced finite element modeling solution, PreSys™, part of the Inventium Suite™ of simulation products. The R3 release of the product will be available to users on October 31, 2011, and will deliver an improved experience for engineers who need to build complex finite element models for nonlinear impact, durability, vibration and thermal analysis.

PreSys™ 2010 R3 has a long list of new or improved features, with one of the most exciting additions being the availability of ‘Part Groups’ which allow the user to drag and drop parts into a group that can be used for visualization, as well as property and boundary condition definitions. “This feature will provide another productivity boost for our users,” comments Tim Palmer, PreSys Product Manager. “Users are able to quickly create and assign groups and change the various attributes of these groups – reducing the number of operations required.”

PreSys R3 also has improved surface data handling and editing features, which allow users to create or modify CAD data within the software.

“We surveyed our users and found that a great deal of their time was used to make connections between the various components of large finite element models. In some cases this may be up to 60-70% of the time required to build a model such as an automotive structure,” comments Palmer. “To address this bottleneck in engineering development, we have created an ‘Auto Spotweld’ feature that allows the user to quickly create a large number of welds at predetermined locations. This has the potential to cut spotweld creation time in half.”

Also part of the Inventium Suite™, VPG™ module updates will also be available on the 31st.  These application specific modules allow users to create unique finite element models and insightful simulations efficiently.  VPG™ modules include Drop Test, Fluid-Structure Interaction and Safety.

For occupant safety analysis, the Safety module allows engineers to position finite element dummy models (included in the software), add seat belts and evaluate effects such as dummy and seat interactions.

Engineering Technology Associates, Inc. (ETA) was established in 1983 by advanced product development engineers working as structural analysts for the world’s largest automotive manufacturers.  ETA’s expertise in the areas of product design and development, vehicle durability, NVH, metal forming, crashworthiness and occupant safety have provided an intimate knowledge of the challenges and needs of the product development engineer.  Proactive in the creation and implementation of new analysis methods and software, ETA is the developer of the Inventium Suite and DYNAFORM.

ETA is pleased to announce the R2 version of its finite element modeling software, PreSys™. Available immediately through ETA and its world-wide distribution network, this version seamlessly interfaces with Moldex3D, the world’s leading Computer Aided Engineering (CAE) software product for the plastics injection molding industry. This new development allows a user to import and edit existing Moldex3D models; to quickly create complex Moldex3D shell models; then export the models for analysis.

By accessing Moldex3D through the user-friendly PreSys™ interface, the model creation process can be automated and streamlined for greater efficiency. PreSys™ offers many flexible and intuitive functions for quickly creating Moldex3D models and editing the designs. The tools offered within PreSys™ include advanced surface handling, automated part thickness mapping functions, as well as runner definition. Ultimately, the PreSys™ environment provides a gateway for users to access these models and use them as the basis for further structural, durability, NVH and impact analyses.

A core solution for finite element analysis engineers, PreSys™ is cost-effective software tool, which also interfaces with popular CAD software products such as CATIA, Unigraphics, ProEngineer, Solidworks and AutoCAD; while also offering CAD-based finite element meshing capabilities. It allows product development engineers and simulation specialists to access design data, quickly create complex finite element models and create insightful simulations.

Building upon its initial release in June of 2010 and the R1 release in October 2010, PreSys™ now offers added functionality and broader potential. The software tool is available on the Windows platform, directly through ETA and its distributor network.
