Zusammenfassung:	Computer-implemented systems and methods are provided for generating accurate grids that can be used for simulation of highly complex subsurface reservoirs, such as fractured subsurface reservoirs. A representation of a fractured subsurface reservoir and an explicit discrete fracture represented within the fractured subsurface reservoir are provided. The representation of the fractured subsurface reservoir is decomposed into polyhedral cells. Interfaces between the polyhedral cells are selected to approximate the discrete fracture explicitly represented within the fractured subsurface reservoir. The selected interfaces are used to produce a grid that can be used for constructing a simulation model of the fractured subsurface reservoir.
