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

poudres cedra

Using recently released software from both companies (ABAQUS
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 . 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.
