ADINA in the Automotive Industry

For over 2 decades ADINA has been extensively used in different industries around the world including automotive, heavy machinery, biomedical, civil and construction, energy, consumer goods, research; among others. In this News, we present an overview of the applications of ADINA in the automotive industry.

For the following reasons, ADINA is an attractive analysis tool for the problems usually encountered in the car industry:

In addition to the built-in model generation and meshing capabilities of the ADINA System, it also provides interfaces to many CAD/CAE softwares for easy importing of the model geometries and meshes. The results of the analysis can be visualized either inside the ADINA User Interface or can be exported to other CAE softwares for visualization purposes. For detailed information please see our page on ADINA CAD/CAE Interfaces.

ADINA offers a comprehensive set of solution capabilities for solving linear or highly nonlinear, static/dynamic, implicit/explicit structural problems which may include large deformations/strains, severe material nonlinearities 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. For more information please see our page on ADINA Structures.

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.

Many problems in the car industry involve interaction between several physical fields such as fluid-structure interaction and thermo-mechanical coupling. ADINA offers a comprehensive array of multiphysics capabilities that can effectively address such problems.

ADINA offers fast and robust equation solvers that can speed up the design cycle for the large finite element models usually encountered in modeling bulky components of the car (e.g., engine blocks). For more details please see our News on ADINA 3D iterative solver.
