ADINA

ADINA is a commercial engineering simulation software program that is developed and distributed worldwide by ADINA R & D, Inc.[1] The company was founded in 1986 by Dr. Klaus-Jürgen Bathe,[2] and is headquartered in Watertown, Massachusetts, United States.

on nonlinear finite element analysis, the proceedings of which are published by Elsevier in the international journal Computers & Structures.

As a result of this agreement, some of ADINA's nonlinear structural analysis capabilities are now offered with NX Nastran by Siemens PLM Software.

The ADINA program consists of four core modules: These modules can be used fully coupled together to solve multiphysics problems, where the response of the system is affected by the interaction of several distinct physical fields (e.g. fluid-structure interaction, thermo-mechanical analysis, piezoelectric coupling, Joule heating, fluid flow-mass transfer coupling, electromagnetic forces on fluids and structures, etc.).

[13] Also, included in the ADINA suite of programs is a graphical user interface (known as the ADINA User Interface, or AUI) with a solid modeler, ADINA-M, for the pre- and post-processing tasks.

Fluid-structure interaction (FSI) results of an aortic heart valve , obtained by coupling the ADINA modules. [ 12 ] The simulation was used to study how sinuses behind the aortic valve leaflets produce vortices that aid in closure with minimal transvalvular pressure .
