LCPC a strong and validated program for engineering purpose.
Today, CESAR-LCPC is equipped with new features to reach a new stage in 3D models.

cesaR-LcPcFinite element software for civil engineering
ModeL geneRation• Complete CAD tools helps to design the initial geometry
of the project. Imports (like dxf) are proposed.• Meshing features :
- Tetrahedral meshing of arbitrarily shaped solids - Regular mesh from super-elements - Sweep, translation, symmetry, rotation… - Mesh refinement: user can densify on locations
where high stresses or deformations are expected.• User-defined macro
LibRaRy of eLeMents• Volume elements: Tetrahedral, hexahedral and wedge • Structural elements : trusses, beams (multi-fibres) are used to
model anchors or bolts. Shells (multi-layered) are used to model diaphragm wall, tunnel lining...
• Interface elements are commonly used to simulate: - soil-structure interaction, - rock faults.
These elements check 3 criterions: Coulomb’s friction, interpene-tration, opening.• Spring elements are necessary for struts or local stiffnesses
soiL behaviouRA wide library of constitutive models is proposed:- Mohr-Coulomb, Drucker-Prager,- Modified Cam Clay, Nova, Vermeer (1982),- Hoek & Brown- Parabolic criterion- Willam-WarnkeThis library is updated when constitutive models are validated after research works.
ReMaRkabLe featuResReinforced materials allows analysis of pile foundation or bolts through homogenisation method.• Loading sets:- Import of flow analysis results as seepage forces- Simplified long-term actions- Import of temperature field as thermal stresses
• Safety factor calculations- c-phi reduction procedure,- ratio of the failure load to the working load.
easy handLing of Phased constRuction• Automatic initialisation of in situ stresses
StAgeD CoNStRuCtIoN- Addition of clusters, like embankments or structure construction- Removal of clusters, like excavations or tunnel openings• Automatic generation of confinement forces
coMPRehensive tooLbox foR ResuLt anaLysis• Deformed mesh• Results picked at nodes and exported to files
• Colour plots with advanced options:- Cross-section planes with interactive positioning- Iso-surfaces in 3D
• Structural results (forces and moments) for beams and shells drawn in 3D view
• 2D graphs:- Evolution in one point as a function of loading- Distribution along an arbitrary line crossing the model
• Listing of calculation and results tables
Hydraulic head evolution nearby a pumping hole
Plane cut in a dam model
Example of pile foundation
