Export Cell Stress The Export Cell Stress command displays the standard Windows Save As dialog box. Select the cell stress you would like to export from the available option buttons, then specify the name of a text file that will hold a collection of lines for each cell stress containing the layer, row, column, values for the different hydrologic properties, and the discharge face for particle tracking. Data from different stress periods are separated by a line containing the number of the stress period. Data are in a tab delimited format. The file can then be used outside of Graphic Groundwater with any program capable of reading a text file. Type in the name of the file. Graphic Groundwater will add the txt extension. Consult Chapter 4 for more information on exporting data.
