GGU-2D-SSFLOW

Modelling of steady-state groundwater flow in horizontal-plane, vertical-plane, axis-symmetrical, two-dimensional groundwater systems using the finite-element method

Capabilities:

  • Powerful mesh generator with mesh refinement and mesh optimisation
  • Import of ASCII-Data
  • FEM mesh coordinates can be imported from a table via the Windows clipboard
  • Consideration of leaky aquifer, seepage lines and unsaturated zones
  • Definition of layer boundaries using fixed values or an interpolation mesh (ASCII data import from the GGU-GEO-GRAPH program)
  • Graphically oriented data input and editor for fixed boundary conditions such as potentials and point, linear or area sources
  • Adopts standard values for kr = f(u) and visualisation as contours
  • Easy-to-use evaluation routines
  • Dynamic damping
  • Colour supported presentation of results such as normal, coloured or 3-dimensional contour lines, tables or circle diagrams
  • Evaluation and presentation of potentials, velocities vx, vy and discharge in userdefined sections
  • Evaluation and coloured presentation of seepage velocities and gradients
  • Evaluation and presentation of groundwater thickness, groundwater-surface distance, confined areas and "dry" areas
  • Evaluation and presentation of flow lines with distance and time increment
  • Calculates a differential contour diagram from two existing groundwater models and visualises them as normal, colour-filled or 3D contours
  • Automatic transfer of steady-state data to the GGU-2D-TRANSIENT and GGU-CONTAM-FE/-RW programs for transient analysis
  • Interface for the program GGU-3D-SSFLOW (3-dimensional groundwater systems)
  • Autosave function
  • User-defined design of output sheet
  • Print or copy screen sections, e.g. for transfer to a word processor
  • Integrated Mini-CAD system for additional annotation of graphics
