Fluent Inc. and ABAQUS Inc. Announce Availability of Fluid-Structure Interaction Capability.

LEBANON, N.H. & PROVIDENCE, R.I. -- Respective leaders in CFD and FEA join forces to deliver an open approach solution to a wide range of multidisciplinary simulations

Fluent Inc., the leading provider of computational fluid dynamics (CFD) simulation software and services, and ABAQUS, Inc., the leading supplier of software and services for advanced finite element structural analysis (FEA), announced today the availability of new software capability for simulation of fluid-structure interaction (FSI). Using recently released software from both companies (ABAQUS 6.5 and FLUENT 6.2), the new FSI capability fills a gap in the market by enabling users to solve complex multidisciplinary design problems involving coupled fluid flow and structural phenomena using leading technologies from their respective domains and backed by the two most highly respected support teams in the industry.

To meet the requirement for higher fidelity simulations, there is an increasing demand for solutions involving two or more disciplines. The joint approach taken by ABAQUS and Fluent uses an independent, open solution for the coupling--MpCCI software from Fraunhofer SCAI, Germany--to enable their individual products to work together to solve a range of important FSI problems. The new FSI capability supports steady-state or transient analysis of thermal-stress and/or mechanical deformation effects, including full bi-directional scalable coupling and takes advantage of the latest parallel processing within each analysis product. Target applications for FSI include, flow-induced vibrations in structures and equipment, fan blade flutter, in-vivo vascular flows, microfluidics, and consumer products design and packaging applications.

"Fluid-structure interaction effects are present in many of our customers' most challenging design problems, and the new FSI capability allows us to engage with those customers to develop robust and reliable modeling approaches," notes Paul Bemis, Fluent's Vice President of Marketing. "We believe that this innovative coupling of best-in-class engineering simulation software is a significant milestone in the quest for an engineering capability that solves real-world FSI problems within industrially realistic timescales."

"Integration with other analysis disciplines is increasingly of interest to our customers," says Ken Short, Vice President of Marketing at ABAQUS Inc. "The open standard approach to coupling that we have adopted here allows us and our customers to focus on best-in-class tools within the structural analysis domain, while providing solutions that address a very wide range of fluid-structure interaction physics. We are very enthusiastic to be working with Fluent to provide a tested and reliable combined modeling capability."

The full set of modeling capabilities in FLUENT 6.2 and ABAQUS 6.5 (including both ABAQUS/Standard and ABAQUS/Explicit structural analysis products) is available for use in coupled FSI simulations. This technology combines the benefits of full nonlinear structural simulation from both ABAQUS products with the unique dynamic meshing capability in FLUENT to account for the effect of structural motion or deformation on the fluid domain.
