FEM-Water Flow
The FEM - Water Flow is used to perform steady state or transient water flow analysis (seepage). Given the material properties and initial conditions at the model boundaries the program computes the evolution and steady state of the pore pressure distribution, degree of saturation in the unsaturated zone, seepage velocities and inflow/outflow through the model. The resulting ground water table can be imported into the standard stress-strain analysis.
Water Flow is an extension module of the FEM program for the analysis of general geotechnical problems.
