Discrete Fracture
Model ID: 691

This example models free flow through a fracture in a block of porous media, where flow in the fracture is much faster than in the matrix block.

• The Darcy's law physics interface is used to model the flow in the the porous block
• The fracture flow is modeled by adding the Fracture Flow feature to the Darcy's law interface. The fracture flow is added to a 2D surface in the 3D domain.

This model is relevant for those interested in subsurface flow and transport of contaminants, including radioactive materials; and oil companies who need to examine fast flow to wells through fractures and slow flow through the tiny pores between grains in a rock or soil.

HYDROLOGY: This example models free flow through a fracture in a block of porous media, where flow in the fracture is much faster than in the matrix block. This plot shows fluid pressure (isosurfaces), the velocity in the fracture (arrows), and Darcy velocities in the matrix block (streamlines).
