Analysis in the engineering world has always been an approximation of reality. In fact, some engineers says it's an approximation of an approximation. But CAE vendors are striving to change that. Among the most recent moves: ABAQUS, known for its finite element analysis capabilities, has joined forces with Fluent Inc., a developer of computational fluid dynamics (CFD) software and services.
They have jointly announced availability of software for simulation of fluid structure interaction, enabling engineers to solve complex multidisciplinary design problems involving coupled fluid flow and structural events.
Says Paul Bemis, vice president at Fluent, "Fluid-structure interaction effects are present in many of the most demanding design problems." He is not alone in his assessment of the multi-physics aspect of many design problems today. ANSYS also touts its multi-physics capabilities, as does ALGOR and MSC.Software. ANSYS, for example, has software that combines structural, thermal, CFD, acoustics, and EMI simulation capabilities.
"Because of the complexity of today's products, there's more of a need for a multi-physics approach," says Bob Williams, product manager at ALGOR. The company's Mechanical Event Simulation software enables engineers to consider motion in their analyses. "You get more than just numbers in your results," he says. "You get what you see."
The ABAQUS-Fluent effort combines the former's nonlinear structural simulation capabilities with the latter's dynamic meshing capabilities to account for the effect of structural motion or deformation. Target applications: flow-induced vibrations.
