Engineering Technology Associates, Inc. (ETA) and NISA Software announced the release of PreSys for NISA 2020 R1 today.  Available immediately through NISA Software, ETA and its worldwide distribution network, substantial updates to the software have been implemented in the release.  The program offers finite element (FE) modeling, meshing, geometry and solver compatibility and Post-Processing. 

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

This offering will allow NISA users to take advantage of PreSys’s streamlined user interface, CAD interoperability and advanced graphics capabilities; thereby improving the overall NISA user experience.

Building upon its initial release in June of 2010 and subsequent releases in 2012 and 2014 and 2016, PreSys now offers added functionality and broader potential with its 2020 R1 Release. The software tool is now available on the Windows platform for 64-bit machines, directly through ETA and its distributor network.

DIFFUSOR2New tool Satisfies Finite Element Analysis requirements of CAD Users 

Troy, MI—Users of Geomagic (Alibre Design), a leading 3D design software solution developed and distributed by 3D Systems (NYSE:DDD), can now purchase the Inventium Suite™ add-on for finite element analysis.  The add-on allows the user to automatically transfer Alibre Design model data into the finite element (FE) modeling tool, PreSys™, of the Inventium Suite™, specify the necessary material and loading definitions, and finally perform analysis with NISA™. 

“This new add-on addresses a segment of the market that has been typically under-served by finite element modeling and analysis vendors,” comments Vipul Kinariwala, NISA™ Product Manager. “Often, they have provided overly simplified versions of their products and the tools have been inadequate to solve all but the most simple simulation tasks. This new product will deliver all of the capabilities found in PreSys™, for FE modeling, and in NISA™, for linear static and eigenvalue analysis.” 

CAD designs can be simulated with this package, allowing engineers to predict and study stress and deflection performance of their product.  This type of analysis allows the designer to reflect on results and improve and optimize designs early in product development.  Significant reductions in product development time/cost and improvements in productivity/efficiency can be achieved. 

The new add-on is available for 3D Systems’ two business class CAD products, Geomagic (Alibre) Design Professional and Design Expert.  The Inventium Suite™ add-on includes NISA™ for linear static and Eigenvalue calculation and PreSys™ for finite element modeling and analysis.  The package is sold together at affordable price-point and is available at (PreSys for NISA) and from selected Alibre distribution channels globally.

Download PreSys for NISA

NISA is now integrated with ETA’s (Engineering Technology Associates, Inc. system-level simulation suite, PreSys. This allows the NISA user to access additional tools which are available in PreSys, including its popular Pre/Post-Processor. PreSys’ Pre/Post offers a wide range of options particularly attractive to users in transportation-related industries. The integration also allows the user to build NISA models and examine analysis results through PreSys.
