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.
