The Pressure Model Program

Given a user-specified pressure gradient and a ground-surface grid model, this program will create a block model (Figure 2) in which the voxel G-values represent the pressure at each voxel midpoint (node).

Figure 2

The program includes upper and lower grid filters (Figure 3) to extract/examine the pressures between two surfaces (Figure 4).

The engineering example shown below (Figure 5) depicts predicted tunnel pressures based on a pressure model filtered with the ModOps / Solid / Filters / Tunnel Clipping program.
