ABAQUS- Element type for coupled pore pressure temperature analysis?

Hello SIMULIA COMMUNITY,

I have a question about ABAQUS: for coupled temperature–pore pressure analysis, do we have to use 3D elements, or can we use 2D elements to simulate coupled pore pressure, stress, and heat transfer? I have already tested C3D8RPT and it works fine, but I am wondering whether it is possible to use 2D elements. 

Thank you
