ETA Releases eta/VPG 3.4 Finite Element Modeling Software and NISA Solver

By DE Editors

Engineering Technology Associates, Inc. has released its finite element modeling software, eta/VPG Version 3.4. This version features the debut of an integrated linear static and dynamic solver, NISA, which allows users to create and visualize advanced simulations within the eta/VPG environment.  

New features include additional advanced meshing tools that allow engineers to quickly develop meshes on complex surfaces, as well as a new capability to import and export basic ANSYS model formats.  

eta/VPG offers five modules that allow users to access the capabilities of LS-DYNA simulation software, in an environment tailored to their industry.

eta/VPG’s commanding PrePost module allows the user to create complex finite element models quickly.   It offers an advanced toolset, auto-meshing tools, and automated spotweld generation—within a zero text-editing environment.  

For mechanical system analysis, the VPG/Structure module includes tools to simulate road surfaces and tire models, as well as analyze vehicle dynamics, system and component durability and noise vibration and harshness (NVH) using LS-DYNA.    

The VPG/Safety module is used extensively in the automotive industry for the modeling of vehicle impact analysis with a complete crash tool library, allowing for accurate vehicle impact, occupant safety and airbag simulations. 

The Drop Test and ALE/FSI modules complete the vertical application tools within eta/VPG.  The drop test functions are used for consumer electronics quality and packaging analysis. The ALE/FSI module is used primarily in military applications for the simulation of blasts and development of blast resistant vehicles.
