PLAXIS 3D is a powerful and user friendly finite element package intended for three-dimensional analysis of deformation and stability in geotechnical engineering and rock mechanics. PLAXIS is used worldwide by top engineering companies and institutions in the civil and geotechnical engineering industry. Applications range from excavations, embankments and foundations to tunnelling, mining and reservoir geomechanics.
PLAXIS 3D has advanced features to tackle modelling challenges in the most complex geotechnical projects, that cannot be solved with PLAXIS 2D.
Complex modelling made easy
Finite element modelling in full 3D has never been easier with a range of CAD-like drawing tools and extrude, intersect, combine and array operations. It’s almost like sculpting.
The user-friendly interface guides the user to efficiently create models with a logical geotechnical workflow. Via Boreholes users can define complex soil profiles or geological cross-sections. In the Structures mode, structural elements, like piles, anchors, geotextiles, and prescribed loads and displacements can be defined. Geometry can also be imported from CAD-files. The automatic meshing procedure creates a finite element mesh almost immediately.
With Staged Construction users can accurately model the construction process, by activating and deactivating soil clusters and structural elements in each calculation phase. With plastic, consolidation and safety analysis calculation type, a broad range of geotechnical problems can be analyzed. Constitutive models range from simple linear to advanced highly non-linear models through which soil and rock behaviour can be simulated. Well proven and robust calculation procedures ensure converging calculations and accurate results. With multi-core calculations and 64-bit architecture PLAXIS can deal with the largest and most complex models.
The versatile Output program offers various ways to display forces, displacements, stresses, and flow data in contour, vector and iso-surface plots. Cross-section tools allow more detailed analysis of results. Data can be copied from tables or via Python based scripting for further processing purposes outside of PLAXIS. The Curve manager enables graph creation, plotting various results types from available calculation data.
