Hello,
I am a student currently studying at Kangwon National University in Korea.
I am working on a two-way coupling study where I first solve a two-phase flow problem, then compute pore pressure from the results, calculate displacement based on the pore pressure, and finally update porosity using the displacement. The updated porosity is then fed back into the two-phase flow simulation.
Since I have only recently started studying this topic, I am still learning and having some difficulties with the two-phase flow calculations. I would like to ask for some advice from the community.
I will share the code I am currently using. When I run the simulation with a large total simulation time, the capillary pressure eventually becomes smaller than the initial value that I set. I suspect that there may be an issue with my initial conditions, material properties, or boundary conditions.
I would really appreciate any suggestions or guidance.
Thank you very much for your help.
