Why choose CESAR?

Key Advantages

  1. Full-featured

  2. CESAR combines mechanics, hydrogeology, heat transfer, and dynamics, required for modelling geotechnical projects.

  3. Easy to handle

  4. 2D and 3D graphical user interfaces of CESAR are designed for a fast understanding of the design process, from geometry construction to results analysis.

  5. Technical support

  6. itech and Université Gustave Eiffel experienced teams provides you with the appropriate level of response and training for your technical questions.

  7. Open tool

  8. Far from being a black box, CESAR is open to data editing, Python scripting and interfacing with third-party tools.

An expertise acknowledged by professionals

CESAR is a finite element software for structural analysis designed and verified by the Université Gustave Eiffel institute (formerly known as IFSTTAR, or LCPC - Central Bridges and Roadworks Laboratory). Under continuous development since 1983 in order to meet civil engineering standards, CESAR is dedicated to underground works, civil works, soils mechanics, hydrogeology and environmental challenges.
In 2003, itech joined the software’s development team and has since brought its expertise in designing powerful and accessible user interfaces. Thus, the close collaboration between IFSTTAR and itech brings CESAR as a highly featured and professional software both in 2D and 3D.
