Discrete Fracture

Application 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 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.

This model is included as an example in the following products:
