Structural analysis model solved with more than 10 million degrees of freedom within a 32bit environment, making it possible for users to solve larger models on relatively low-cost hardware.
Ansys has solved a structural analysis model with more than 10 million degrees of freedom (10,501,650 DOF) within a 32bit environment, making it possible for its customers to solve larger models on relatively low-cost hardware.
In May, the firm became the first engineering simulation company to solve a structural analysis model with more than 100 million DOF within a 64bit environment, endowing the power to solve models of aircraft engines, automobiles and other complete systems.
Now, in a joint effort with Linux Networx, the 10 million DOF structural analysis problem was completed on an 11-processor Linux Networx Evolocity cluster with Intel Xeon chips and the Linux operating system.
DOF refers to the number of equations being solved in an analysis giving an indication of a model's size.
Previously, only about 1.5 million DOF undistributed could be solved within a 32bit environment.
"Our customers have shown an interest in solving moderate-sized problems on very cost-effective hardware", said Mike Wheeler, VP and General Manager at Ansys.
"Our new distributed algorithm is much more memory efficient, which enabled us to solve such a large problem with a modestly sized 32bit cluster".
"As a technological leader in cluster computing, Ansys is committed to solving increasingly larger model sizes and providing a method for our customers who want to continue to push the traditional analysis boundaries".
"This latest success combines the long-standing power of the Ansys solvers with the scalability of the Workbench environment".
Linux Networx plans to ship turnkey systems preconfigured with Ansys to reduce startup time, increase productivity and ease IT concerns for Ansys customers.
"With Ansys' experience of solving large CAE models and our expertise with parallel computing, it is fitting that we are working together on this achievement", said Eric Pitcher, VP of Technical Marketing at Linux Networx.
"By delivering clusters optimised for CAE modelling, Linux Networx and Ansys can help customers achieve faster simulations, impressive cost savings and higher productivity".
