Fract_002 Discrete Fracture Modelling
Contents
Introduction
The aim of this example is to demonstrate procedures for importing the modified fracture data file from Fract_001 and running a simple steady-state flow (solved in a single time step) across the fractured medium. The simulation domain is the same as the example in Fract_001. In this example, we define a set of boundary conditions for the fractured sample as follows. Higher pore pressure is prescribed on the east and south boundaries, whereas lower pore pressure is prescribed on the west and north boundaries. The history of fluid volume and flow rate on the latter two boundaries are recorded. In addition, all surfaces are prescribed with symmetry boundary conditions, i.e., displacement is restricted in the direction normal to the individual surface. The mesh size is set to be 10m.
