GRAPHICAL INPUT OF PROJECTS
A project geometry is modelled using a top view approach. The input of soil data, structures, construction stages, loads and boundary conditions is based on convenient CAD drawing procedures, which allows for a detailed and accurate modelling of the major geometry. From this geometry a 3D finite element mesh is generated.
BORE HOLES
Soil layers are defined by means of bore holes. Multiple bore holes can be placed in the geometry to define a non-horizontal soil stratigraphy or an inclined ground surface. Plaxis automatically interpolates layer and ground surface positions in between the bore holes.

Finite element methods have become ever more important to engineers as tools for design and optimization, now even for solving non-linear technological problems. However, several aspects must be considered for finite-element simulations which are specific for non-linear problems: These problems require the knowledge and the understanding of theoretical foundations and their finite-element discretization as well as algorithms for solving the non-linear equations.
