Displacements in UDEC model

This example demonstrates the use of UDEC to model a tunnel excavation in jointed rock mass. In this demonstration, geometry sets are used to create the tunnel geometry. The Barton Bandis model is used to represent the joints. The "block solve relax" command is used to simulate the pre-relaxation of the rock mass while excavating the tunnel.
