A038 GROWING REGION TECHNIQUE APPLIED TO GRID GENERATION OF COMPLEX FRACTURED POROUS MEDIA Abstract 1 This paper describes a new methodology to generate unstructured grid for complex fractured porous media. A growing region technique is used to perform a volume partitioning of the space between the fractures. Then the fractures are identified as interfaces between matrix control volumes. The control volumes are represented by convex polygons in 2D and convex polyhedra in 3D. The methodology is illustrated with 2D and 3D examples. For a 2D example the presented gridding technique is combined with an efficient discrete fracture model to perform
