Claim One:
1. A method comprising: identifying a discrete natural fracture in a three-dimensional graphical environment within a graphical user interface, wherein the three-dimensional graphical environment comprises a three-dimensional grid model representing a reservoir located in a subterranean formation, and wherein the three-dimensional graphical environment further comprises a multisegment model representing the discrete natural fracture in a first two-dimensional region within the three-dimensional graphical environment; defining at least one connection for a fluid communication linking, within the three-dimensional graphical environment, the multisegment model to the three-dimensional grid model; defining boundary conditions for the multisegment model; and solving the multisegment model subject to the at least one connection for the fluid communication and the boundary conditions to provide values for fluid flow in the first two-dimensional region.
