Steady-state groundwater seepage and true flow nets by finite elements: confined and unconfined 2D and axisymmetric flow, iterated phreatic surfaces and seepage faces, rainfall recharge with an unsaturated zone, pore-water-pressure fields for slope stability, and curvilinear-square flow nets.
Solvers
— confined/anisotropic FEM seepage from head and streamline boundary conditions
— unconfined flow with an iterated phreatic surface, seepage face and optional rainfall recharge
— axisymmetric flow to a pumped well (Stokes stream function)
Flow nets & plots
— curvilinear-square flow net (equipotentials + streamlines) with reported Q
— field maps: head, pore pressure (with capped suction), speed, gradient
Fields & quantities
— pore-water-pressure function (with tension cut-off) for slope stability
— flux across a boundary of the solution
— exit hydraulic gradient at a discharge boundary
Problem registry
— store and recall named problem instances
— clear stored problem instances
