Recent development of fluid–structure interaction capabilities in the ADINA system

Abstract

The ADINA system has been developed in recent years into a complete system for the analysis of solid, fluid and coupled problems. Fluid flows can be modeled as Navier–Stokes incompressible, slightly compressible and fully compressible flows. They can also be modeled as porous medium flows. Structures can be modeled as 2D/3D solids, beams or shells. The response of the structure can be linear or nonlinear, and can also include contact effects. The fluid and structure can be coupled through their interface (FSI), porous media (PFSI) or thermal materials (TFSI). Both iterative and direct solution procedures can be used for solving the fully coupled system. These capabilities, together with the extensive boundary conditions and material models, and the user-friendly graphical system for pre- and post-processing (AUI), make the ADINA system a powerful tool for engineers and researchers.
