Additional measures are taken to improve solution efficiency for transient problems, including automatic time step adjustment and adherence to preset ranges of the Courant and Peclet numbers. The water content term is evaluated using the mass conservative method proposed by Celia et al. The location of discretization nodes can be graphically edited by a user to optimize the thickness of different elements. The program includes controls to allow a user to build an application specific flow and transport model, and to perform graphical analyses on the fly. Both input and output can be examined using graphical tools.
File management is handled by a sophisticated project manager.
Peripheral devices supported include most popular types of printers and plotters. A small catalog of soil hydraulic properties is included in the program. Extensive context-sensitive, online Help is part of the interface.
