Why Akantu ?

Finite-Element library dedicated to damage, contact and micro-mechanics

Akantu fulfills the requirements of genericity, robustness and efficiency needed for intensive simulations

Accuracy and speed combined together

Akantu means a little element in Kinyarwanda, a Bantu language. It is also an opensource object-oriented Finite Element library. Akantu was born with the vision to associate flexibility, robustness and efficiency, thanks to its characteristic architecture. A unique C++ object-oriented design combines high-level classes and interfaces with optimized critical loops acting on degrees of freedom. It makes Akantu‘s unique implementation both object oriented and vectorized.

Akantu’s 4.0 is out!

Akantu has reached a new milestone with the official release of Akantu 4.0 ! The repository has officially migrated to GitLab. The development team is proud to introduce the new python interface which greatly improve Akantu’s accessibility. In addition, tutorials based on the python interface are available to help newcomers to the Akantu community to get started ! Two major features are introduced in this version: (1) The phase field model a mesh-independdent damage model for brittle fracture that can handle complex crack networks (2) The contact mechanics model, handling the contact between bodies
