ADONIS is Free Finite Element Software for Geo-Engineers. The goal of the ADONIS development is to improve the modeling and computational simulation in geotechnical engineering.

ADONIS is an easy-to-use yet powerful geotechnical-engineering tool for the linear and nonlinear analysis of geotechnical problems. It features a full graphical user interface (GUI) for pre-processing or post-processing and uses fully automatic mesh generator to create complex finite element meshes. The graphical interface enable a quick generation of complex models, and the enhanced output facilities provide a detailed presentation of computational results.
