A tutorial showing how to create an unstructured mesh in FLAC3D 7.0 using the extruder pane.
In this tutorial we will take a look at the different boundary conditions available to the user, and we will go over some examples of different scenarios in which they would be used.
In this example, a pile of earth is modeled overlying undulating ground. This tutorial demonstrates how a FLAC3D model mesh can be easily created using DXF geometries and the ZONE DENSIFY command. How to differentiate parts of the model into separate GROUPs using DXF geometries and the GEOMETRY-SPACE range logic is also demonstrated.
Caving, ground surface deformations and the influence of structures when mining by sublevel caving (paper in Swedish)
With increasing depth, higher stress and more difficult mining. With increasing depth is there more ground surface effects or less?
