Each node has three translational degrees-of-freedom. The software uses numerical integration to prevent shear locking.

Tutorials emphasize proper corner node selection to avoid "negative volume" errors when generating custom solid meshes.

PLAXIS is the industry standard for 2D and 3D geotechnical modeling. Tutorials typically cover:

Analyzing embankments reinforced with geotextiles, tunneling, excavations, and offshore foundations.

Bentley's GeoStructural Analysis Software is a collection of modules for specific tasks:

For structural problems involving general 3D stresses—like concrete dams or complex rock masses—STAAD.Pro uses eight-noded isoparametric solid elements.

Using output programs for contour plots of displacements, stresses, and flow data, or using Python-based scripting for automation.

Defining material models (e.g., soft clay, granular soil), setting up plain strain or axisymmetric models, and generating high-precision mesh with 15-noded elements.
