Assign Water
If you are using Water Surfaces or Water Grids to calculate pore pressure, they must be assigned to materials.
- Water Surfaces are used for calculating pore pressure if the Groundwater Method = Water Surfaces.
- Water Grids are used for calculating pore pressure if the Groundwater Method = Water Grids.
There are two possible ways to assign water surfaces or water grids: in the Material Properties dialog OR with the Hydraulic Assignments dialog.
Material Properties
Water Surfaces or Water Grids can be assigned to materials under the Water Parameters tab in the Material Properties dialog.
Hydraulic Assignments Dialog
To assign water surfaces or water grids with the Hydraulic Assignments dialog:
- Select the Groundwater
workflow tab. - Select Assign Water to Materials
from the toolbar or the Groundwater menu. - In the Hydraulic Assignments dialog, there are two possible methods of assigning water surfaces or grids:
- Select a Water Surface or Water Grid from the combo box at the top of the dialog; select the checkboxes for the desired materials; select the Apply to Checked Materials button. This is the fastest way to assign a water surface or water grid to multiple materials.
- OR you can use the combo box beside each individual material to select a Water Surface or Water Grid for the material.
- When you are finished assigning select OK.
The Hydraulic Assignments dialog is an alternative method of assigning pore pressure calculation to materials. It can be particularly useful if you need to assign a water surface or water grid to multiple materials, since you can select multiple materials and assign water with one mouse click, rather than having to go through the Water Parameters tab for each material in the Material Properties dialog.
