The program handles a maximum of 20 aquifers and 50.000 nodes (25000 elements) per aquifer. Confined, leaky, phreatic and anisotropic aquifers can be modeled. Full graphical control makes the otherwise time-consuming and error-prone process of grid generation and data input easier. The same holds for the display of results: contour maps, 2- or 3-dimensional flowlines and flow vectors. Further options include interactive grid adaptatisection.ons, water budgets, travel times and the automated calibration of steady-state models.
