Modeling fracture flow in stress field in COMSOL

[Atr cheema]

I am new to COMSOL and I want to model fluid flow in stress field. As starting point I want a simple 2D box having a fracture from right to left while pressure gradient vertically. I want to know the threshold value of that pressure from top which allows flow of fluid in fracture. Can anyone please suggest me which modules of COMSOL should I be using. I see simple fluid flow in fracture examples but not where impact of pressure controls the flow!

For this simulation, you should use the CFD Module in COMSOL. This module will allow you to simulate a variety of different flow phenomena, including the effects of a pressure gradient on the flow of a fluid through a fracture. You can also set up a boundary condition to represent the pressure at the top of the box, and then vary this value to see how it affects the flow. Additionally, you can set up a parameter sweep to systematically vary the pressure and observe the resulting flow patterns.
