Step 2: Properties
This step assigns hydraulic properties (hydraulic conductivity and porosity) to model elements.
Two options are now available. To randomly assign hydraulic conductivity and porosity values to the grid, click the “Randomize” check box and then click “OK”. Each pair of triangle elements (forming a square) will be randomly assigned one of five colors corresponding to the properties in the dialog box.
Alternatively, properties can be manually assigned to the grid as follows:
Additional zones with the same properties may be defined by drawing additional polygons. To specify a zone with different property values, click the "Properties" button again to bring up the dialog box and click on a different color icon. Then click "OK," draw a polygon as before. The newly selected elements now are filled with the new color. Drawing mistakes can be rectified by overdrawing with another zone. Any part of the mesh not covered by a polygon will have properties corresponding to the white color.
