This paper describes grid generation algorithms for simulating flow and transport in fractured porous media. The methods are designed to only capture details of the fracture network geometry larger than the specified grid resolution. The final grids honor fractures approximately while maintaining good cell quality. Improved representations of the input geometry can be obtained by generating a new grid with finer resolution. Several numerical examples are presented in two and three dimensions that demonstrate that the algorithms are robust and practical for industrial applications.
