3-D Tunnel Analysis

A tunnel excavation according to NATM (New Austrian Tunnelling Method) is examined as an example of a three-dimensional analysis with volume elements.
An accurate consideration of the partitioning in group numbers is required a priori, because the groups have to be controlled separately during the various construction stages.You will find the input data file viaTEDDY > help > examples... > ase > english > ase14_tunnel_3d.datThis example is documented in detail at the ASE manual - chapter 5.14Level of difficulty: advanced
