Each element in the 2D mesh is assigned a material ID. The material properties are assigned to each element using these IDs and a list of material properties. The material properties specific to SEEP2D are entered using the Material Properties command in the SEEP2D menu. This command brings up the SEEP2D Material Properties dialog. The items in the dialog are as follows:
The currently defined materials are listed at the top of the dialog. The values for a material are entered by selecting the material and editing the values in the lower part of the dialog.
The hydraulic conductivity in the two major principal directions and the angle from the x-axis to the major principal axis are entered in the Soil Coefficients section. These hydraulic conductivity values represent the hydraulic conductivity for saturated conditions.
If the Ven Genuchten Saturated/Unsaturated option has been selected in the SEEP2D Analysis Options dialog, the Van Genuchten alpha and n-value numbers must be defined.
If the Saturated/Unsaturated with Linear Front option has been selected in the SEEP2D Analysis Options dialog, the minimum pressure head (ho) and minimum relative conductivity (kro) values must be defined.
