Introduction

ADINA R&D, Inc. (USA) was founded in 1986 by Dr. K. J. Bathe (Author of “Finite Element Procedures) and associates.

FEM (Finite Element Method) & FVM (Finite Volume Method) for the analysis of solids, structures, fluids and fluid flow with structural interactions coupling with Multiphysics.

ADINA 8.7.5 was released in December 2011.
