Coupled Evolution of Deformation, Pore Fluid Pressure, and Fluid Flow in the thrust-fold mountain belt ？ about underworld2 HOT 4 OPEN

Yes, the two can be coupled. You can set up each material to have a specific permeability or you can have a mesh/swarm variable that describes the permeability in the model that is used to calculate the fluid flow. The pressure field can be obtained from the Stokes flow and then used in the Darcy solve to determine the groundwater flow.

Hi @ch9411, it is possible. We have the stokes flow for the geodynamics, advdiff for temperature evolution and a Darcy solver for fluid flow.

Thank you for your response. Due to the limited information available on groundwater flow, especially within the context of UW, we would like to inquire about the setup of permeability and fluid pressure boundaries when using Stokes flow. Can the external fluid pressure vary with deformation (in other words, coupling)? We look forward to your reply. Thank you.

Your response has enlightened me, but as I am a beginner, I am not very familiar with the mechanisms involved. And, we have not found the keywords related to setting the permeability coefficient. Could you please provide a simple example or code? Thank you very much!
