Water Pressure Grid

If the Groundwater Method = Water Grids then you can assign a water grid (total head, pressure head or pore pressure) to calculate the pore pressure for a material.

A Water Grid allows you to model the groundwater pore pressure distribution by defining the total head, pressure head or pore pressure at a grid of discrete XYZ locations. From the data at the grid points, the pore pressure at any point in a material can be determined using the specified Interpolation Method.

Water grids are created with the Add Water Pressure Grid option.


To assign a water grid to a material, select the name of the grid from the Grid drop-list. If water grid(s) have been defined, all currently defined grids will be listed in the Grid drop-list. By default Grid = None (no water grid is assigned). If Grid = None then pore pressure will be zero for that material.

There are three types of Water Grid that can be defined - Total Head, Pressure Head or Pore Pressure. See the Water Grid Overview topic.
