Cross-Sections Graphically

Inserts a Cross-Section graphically using the mouse.

In the HYDRUS-2D software package one could click on any two points of the transport domain to display results of selected variables between those two points, i.e., along a specified cross-section. The exact location of the cross-sections was not saved and they had to be redefined whenever a new graph was required. In HYDRUS one can define the cross-sections and save their locations so that graphs along the cross-sections can be recalled at any time by simply clicking on them. Graphs along pre-defined cross-sections can be displayed for both the initial conditions and the output results. For example, if a plot of the pressure head along a predefined cross-section at a particular time is needed, one must display the pressure head outputs, find a particular time, and then click on the predefined cross-section. The graph is displayed instantaneously. Specifying the cross-section within a two-dimensional domain is straightforward. For three-dimensional domains one can use the Cross-Section dialog window for this purpose.
