Dassault Systemes Announces ABAQUS® Version 6.6 for Advanced Finite Element Analysis; Added Performance, New Analysis Features, and Usability Improvements Extend the Value of ABAQUS Software for Simulation across Industries

Business Wire, April 12, 2006

--Parallel performance improvements. In ABAQUS/Explicit, 16 to 32 processors can now be used effectively for certain classes of large models to reduce turnaround time and to increase throughput. In ABAQUS/Standard, a new distributed memory parallel sparse solver is introduced, providing good scaling for many problems on up to 8 processors. Large classes of simulations in both ABAQUS/Standard and ABAQUS/Explicit can now be run on distributed memory cluster configurations.

With more than 115 major improvements, ABAQUS Version 6.6 achieves a new overall standard for performance, usability, and simulation fidelity, while upholding a distinguished reputation for flexibility and reliability.
