Geotechnical engineering
CESAR is a calculation software enabling modelling and analysis of geotechnical problems. Proven, powerful and user-friendly, it covers a wide scope of soil and rock mechanics applications (deformation, stability...). It is a valuable tool for geotechnical engineers for embankment, excavation, foundation or tunnel studies, and more.
Deformation and stability
CESAR is bundled with an extensive constitutive model library (linear and non-linear elasticity, Mohr-Coulomb, Hardening Soil, Cam-Clay...) relevant to the study of deformations and stresses in soil masses.Consolidation analysis (coupling) allows the study of primary and secondary settlement of soil masses.
Finally, CESAR features the required calculation procedures in order to obtain safety coefficients in regards to stability (c-phi reduction procedure) or stresses (e.g. limit pressure search).

Soil-Structure Interactions
CESAR offers intuitive and comprehensive tools for simulating consecutive passes of embanking or excavation, integrating realistic construction stages. Numerous pre-defined elements are available to model structures and their interaction with the soil mass, or the reinforcement of soil masses (anchors, geogrids, bolts...).These tools enable geotechnical engineers to predict ground movements induced by and endured throughout construction.

Groundwater
CESAR is bundled with the required tools for modelling the water table as a mechanical load. The user can also perform independent hydrogeological calculations: transient and steady state flows, in saturated or unsaturated soils (van Genuchten and Gardner models or user-defined saturation curves).Thus, the user is able to model complex hydrogeologic problems with varying water levels and flow conditions such as dewatering or groundwater control.
