History

The development of ADINA was started in 1974 by Dr.

, shortly after he finished, as the principal developer, the finite element programs SAP IV and NONSAP. In 1986, Dr. Bathe founded ADINA R & D, Inc. in Massachusetts, USA, and he continues to lead the development of ADINA as technical director of the company. ADINA R & D performs all developments of the ADINA program in-house, and focuses on reliable and efficient finite element procedures. ADINA R & D sponsored twelve bi-yearly academic conferences at M.I.T. on

Software Architecture

ADINA is the acronym for Automatic Dynamic Incremental Nonlinear Analysis. The ADINA program consists of four core

modules Broadly speaking, modularity is the degree to which a system's components may be separated and recombined, often with the benefit of flexibility and variety in use. The concept of modularity is used primarily to reduce complexity by breaking a sy ...

: * ''ADINA Structures'' for linear and nonlinear analysis of solids and structures * ''ADINA Thermal'' for analysis of heat transfer in solids and field problems * ''ADINA CFD'' for analysis of compressible and incompressible flows, including heat transfer * ''ADINA EM'' for analysis of electromagnetic phenomena 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,

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. The AUI can be used to import solid models, and finite element models in Nastran format, providing an interface to many
