ADINA (Automatic Dynamic Incremental Nonlinear Analysis) from ADINA R&D, Inc. is a unified software system for comprehensive finite element analysis of structures, heat transfer, fluids, electromagnetism, fluid-structure interactions and multi-physics. ADINA offers a comprehensive set of solution capabilities for solving linear and highly nonlinearstatic/dynamic structural problems which may include large deformations/strains, severe material non-linearities and contact conditions.

ADINA also offers a wide range of material models and reliable and efficient element technology, which is crucial in obtaining reliable solutions in complex analyses usually encountered in the automotive industry. In ADINA, different physical fields can be modeled within the same software environment. Analysts can solve structural, heat transfer and CFD problems seamlessly inside the ADINA System without the need to license other programs.

The development of ADINA was started by Dr. K.J. Bathe in 1974. In 1975, Dr. K.J. Bathe joined the Department of Mechanical Engineering at the Massachusetts Institute of Technology, MIT. In 1986, he founded ADINA R&D, Inc. for fostering the development of the ADINA and leads the development of the ADINA system.

The ADINA Systems used widely in many fields of application, including the automotive, aerospace, manufacturing, nuclear and biomedical industries, civil engineering applications and research. Some of the nonlinear structural analysis capabilities of ADINA are offered as Solution 601/701 of NX Nastran, by Siemens. 

As known NX Nastran Advanced Nonlinear solver SOL601 and SOL701 is retired from Siemens Product Portfolio with the end date December 2021. For all who will continue to work with those solvers we offer ADINA Structures solver from ADINA R&D Inc., which supports all SOL 601/701 capabilities with even more very interesting solution capabilities. We summarized all ADINA Structures capabilities in the bellow presentation


Direct Femap interface to ADINA

To use Femap with ADINA allows many ADINA capabilities, including CFD and FSI analyses, to be used with Femap. This interface works completely within the Femap environment and requires minimal learning for people already familiar with Femap. Loads, boundary conditions, constraints, contacts, material and element properties, and even ADINA control settings are all defined and saved in the Femap model. The ADINA solver is activated within Femap and runs in the background with a clear indication when the job is completed.

The current interface to Femap supports the following analysis types:

  • Structural analysis - linear and nonlinear, large deformations and strains, static, implicit and explicit transient, various nonlinear material models and contacts
  • Dynamics - frequencies and mode shapes with or without contact, mode superposition in linear and nonlinear analyses, crash and crush simulations
  • CFD - incompressible flow, laminar and turbulent flows, with or without heat transfer, wall, inlet and FSI boundary conditions, initial conditions, sparse and algebraic multigrid solvers.
  • One-way FSI analysis - CFD analysis is run first and the forces exerted by the fluid on the structure at the FSI boundaries are used in a subsequent structural analysis to compute the displacement and stresses in the structure. Completely different meshes can be used for the structure and the fluid, which is an important requirement because the CFD solution requires generally different and many more elements than the structural solution.

In ADINA Brief, the direct Femap interface to ADINA is demonstrated for a propeller model, that involves glued connections (which allows different meshes for the glued components), contact and a preload bolt in static analysis followed by a frequency analysis.
