Plaxis Manual -

The option extends PLAXIS beyond conventional consolidation (Biot) theory by integrating transient groundwater flow and mechanical deformation simultaneously within a single time-stepping scheme. This feature is essential for problems where pore pressure generation and dissipation are intrinsically linked to stress changes, and where traditional uncoupled or partially coupled approaches are insufficient.

This is a tiny section of the manual that causes massive errors. PLAXIS has default numerical parameters (tolerances, iteration methods) that are fine for standard problems but terrible for highly nonlinear problems (like pull-out of a suction caisson). plaxis manual
