ESI Group Announces New Release of VA One Noise and Vibration Simulation Software

ESI Group, pioneer and world-leading solution provider in virtual prototyping for manufacturing industries, announces the latest release of VA One. VA One is a complete solution for simulating noise and vibration across the full frequency range, which seamlessly combines Finite Elements, Boundary Elements, and Statistical Energy Analysis (SEA) in a single model. This new release includes significant performance and productivity improvements, along with new functionality for full spectrum modeling of acoustic ducts.

Performance enhancements

The SEA and Hybrid modules of VA One have been optimized to make increased use of the multi-threading capabilities of multi-core desktop machines. Speedups of up to 4.5x have been observed for processing simulations on certain models running on quad-core desktop machines, when compared with previous versions of the software. The speedups were made possible because of the modern software architecture of VA One, and through the use of the latest Intel tools for software development.

“Intel® Parallel Studio XE 2011 is a comprehensive tool suite that provides an innovative threading assistant, compiler and libraries, memory threading error checker, and threading performance profiler,” said James Reinders, Director at Intel. “We are pleased to have collaborated with ESI Group on the performance enhancements in VA One 2011 and their utilization of Intel® Parallel Studio XE 2011.”

Productivity enhancements

The latest VA One release includes a large number of productivity enhancements, including new methods for quickly editing and updating the attributes of multiple objects in a model. This reduces model building time and provides more time for solving noise and vibration problems.

Modeling noise in ducts across a broad frequency range

The noise transmitted by duct networks is important in many applications. The new VA One release includes a unique functionality for quickly modeling the transmission loss of complex ducts with arbitrary cross-section, both above and below the plane-wave cut-on frequency.

“We are pleased to announce the release of VA One 2011,” said Dr. Phil Shorter, Director of Vibro-Acoustic Product Operations at ESI Group. “The performance enhancements in this release will benefit all VA One users and were obtained through the use of a modern software architecture and close collaboration with Intel.”
