The user-friendly PLAXIS interface guides users across several modes to efficiently create models with a logical geotechnical workflow. Benefit from fast and efficient finite-element model creation via CAD-like geotechnical drawing applications. Utilize multiple boreholes in Soil mode to quickly create ground profiles or geological cross-sections. In Structures mode, add structural elements like plates, discontinuities, piles, and prescribed loads or displacements etc. For tunnel solutions, a designer wizard offers quick creation of tunnel cross-sections, reinforcements, tunnel lining, and loading conditions. Mesh mode features automatic and manual mesh refinements, automatic generation of irregular and regular meshes, and capabilities to inspect the mesh quality. It is also possible to import geometry from CAD files, or fully automate model generation by using Python-based scripting.

Accurately model the construction process by (de)activating soil/rock clusters and structural elements in each calculation phase in Staged construction mode. Perform the relevant geotechnical analysis by selecting between plastic, safety, and consolidation analysis as well as dynamic or fully coupled flow-deformation analysis. Employ various constitutive models ranging from simple linear to advanced highly nonlinear models that allow accurate simulation of most soil and rock types. Well-proven and robust calculation procedures ensure that calculations converge and provide accurate results for the most common or complex models, excelling in settlement, thermal, groundwater flow or dynamic analysis.

The versatile Output program offers various ways to display forces, displacements, stresses, velocities, accelerations, temperature, and flow data shown in contour, vector, and iso-surface plots. Cross-section capabilities allow areas of interest to be inspected in more detail, and data can be copied from tables for further postprocessing in other software. The curve manager enables the creation of graphs that can plot various results across a selection of calculation phases. Python scripting allows Output results to be used in connected external applications or automated modeling workflows in the PLAXIS ecosystem.
