ESI Group releases AutoSEA 2003

ESI Group have announced the release of AutoSEA 2003. AutoSEA2 2003 includes a new general laminate subsystem with visco-elastic material properties, enables predictions of the damping added by acoustic treatment layers, including foam-backed carpet, dash barriers and headliner trims, and now supports object grouping and provides new features for model quality checking. To help diagnose the noise paths and to identify the design parameters which are controlling the predicted noise levels, the energy level “thermogram” has been enhanced.

Happy Birthday to noiseboard.com

It has been one year since noiseboard.com was started. There have been over 36,000 hits over the year. The tallys in the download section show that many people find the articles and papers useful. If you do find something useful, please don’t hesitate to drop me a note (and no, your email or fake email address will not get onto a spam list.)

I am currently preparing a short article that compares the use of ANSYS for acoustic analyses using a P4 computer, with and without the Hyperthreading, under windows and Linux, using version 7 and an older version. The first results show that there is little difference between HT and not HT, but a big difference between an older version and V7.0.

LMS releases SYSNOISE V5.6

LMS International have released version 5.6 of LMS Sysnoise, boundary element analysis software for prediction of noise and vibration. This version adds new capabilities to predict flow-induced noise and aero acoustic phenomena.

ANSYS v7.1 is out

ANSYS have released version 7.1. Of particular interest to acoustic and vibration researchers are the improvements to the coupled field and modal analyses. Using the Mesh-based parallel Code Coupling Interface (MpCCI), you can now perform fluid-solid interaction analyses using ANSYS and a third-party CFD code, even if the meshes are dissimilar. The sparse solver and Block Lanczos eigensolver now support parallel processing for the Linux 32-bit platform, when using four to eight processors on this platform, you will improve the processing speed by a factor of 3 to 3.5 times that of a single processor.
