| Abstract | This paper describes the addition of integrated stress analysis into the TOUGH2 code. The goal is to provide a fully coupled analysis capability that takes advantage of the present flow and heat transfer analysis in TOUGH2 and extends this in a consistent manner to incorporate stress. The stress analysis is performed using the dual of the TOUGH2 mesh for the finite element stress analysis. This leads to an elegant and efficient coupling, that minimizes changes to the TOUGH2 code, while adding new stress solution capability. |
