This program is used for analyzing water flow in a stationary or transient state (seepage). By applying material properties and initial conditions at the model's boundaries, the program calculates the development and steady state of pore pressure distribution, saturation degree in the unsaturated zone, seepage velocity, and inflow/outflow within the model. The final groundwater table can be imported into a standard stress-strain analysis. Water flow is an additional module of the FEM program for analyzing general geotechnical problems.
