GEO5 FEM - Water Flow

The FEM - Water Flow is used to perform steady state or transient water flow analysis. GEO5 Water Flow is an extension module of the FEM program for the analysis of general geotechnical problems. The main program features are:

• Material models for the unsaturated zone:
  • Log-linear model
  • Van Genuchten model
  • Gardner model
• Database of material parameters based on USCS classification and soil consistency
• Boundary conditions:
  • Impermeable line
  • Permeable line
  • Prescribed pore pressure
  • Prescribed inflow / outflow
  • Seepage surface with conditions not known in advance
• Point hydraulic conditions:
  • Inflow / outflow
  • Pore pressure at a point
• Possibility to represent partially permeable interfaces (contacts) and beams
• Introduction of drains and preference paths
• Flexible time step adjustment for effective computation
• Import and export of the geometry and resulting ground water table in DXF format
• Sharing the resulting ground water table between projects via GeoClipboard
• Lucid representation of pore pressure distribution, flow velocities, and ground water table
