Ground Surface Definition

The Ground Surface in UnWedge acts as an upper boundary for Perimeter Wedges. Any Perimeter Wedges extending beyond the Ground Surface will be truncated.

A ground surface can also be used as a piezometric line as explained in the Water Pressures topic. It is also used as the Ground Surface Elevation (instead of user input) in a Gravity Field Stress Analysis.

Bolts are not allowed to penetrate through a Ground Surface.
