Advanced Tool for Engineering Nonlinear Analysis. A user friendly software for nonlinear analysis and design of reinforced concrete structures.
ATENA user Richard Malm says in his Ph.D. thesis:
"One advantage using ATENA for the finite element analyses is that it calculates all material properties based on the cube strength with equations from Model Code 2010. Another great advantage with this program is that it is specially designed for concrete, which makes it easier for the user since good default values are given. The main advantage is that, even though the analyses described severe cracking, the program never had problems finding a convergent solution. A novice user can rather easy create advanced models in ATENA."
With ATENA You can simulate real behavior of concrete and reinforced concrete structures including concrete cracking, crushing and reinforcement yielding. ATENA gives you the power to check and verify your concrete structural design in a user friendly graphical environment.
Proved by over 2500 installations worldwide.
ATENA is based on FEM analysis. It belongs to the category of advanced analyses software such as ABAQUS (SIMULIA) or ANSYS, but it focuses on reinforced concrete structures and brittle materials. We are strongly devoted to provide best specialized software for advanced simulation of all types of concrete and reinforced concrete structures.
ATENA can be also compared to standard concrete design software such as Dlubal, Sofistik or ETABS. While these programs allow engineers to design structures quickly according to various national design codes, ATENA helps engineers in better understanding what is the real structural behavior or true load carrying capacity.
We are pleased to announce the release of ATENA 2025, featuring a new Engineering Preprocessor.
This new version ATENA 2024 brings a new pre-processor that combines the robustness of ATENA Science with the simplicity of ATENA 3D Engineering.

Arbitrary reinforcement arrangement can be easily included in the model either as discreete bars or as smeared reinforcement.
Bond failure can be activated just by single click. Prestressing and external cables are supported as well.
Only in ATENA the engineers can observe the deformation shape and the cracking pattern even during analysis using the unique and extensive runtime visualisation capabilities.
ATENA supports realistic visualisation of cracks and cracking pattern in all stages of the nonlinear analysis a post-processing. Cracks can be displayed not only on the surface, but also in the interior. For more realistic visualisation, only the visible cracks can be filtered.
Try ATENA for 30 days and unlock the power of advanced simulation. With the free trial, you and your team can experience the full set of capabilities offered by our powerful software. Read More about the trial licence.
We strongly support our users in their analytic work with ATENA. Support is mainly provided by email and phone calls. The solutions to many questions can also be found in our FAQ & Online Forum. New versions of ATENA are released every year.
Maintenance is provided for free for one year after the software purchase. After that, it can be prolonged at an annual rate corresponding to 15 % of the program price.
