Abstract
We present a new method to discretize inclined 3D fractured media for subsurface flow and transport simulations. We first discretize the fractures and generate a 2D finite element mesh for each fracture. Then, the mesh of fractures is analyzed by searching and treating critical geometric configurations. Based on that search, the method generates a mesh quality and allows for including finer grids. The method is validated by solving a solute transport problem in fractured porous media. The results show that the method (i) adequately represents the fractured domain by maintaining the geometric integrity of input surfaces and geologic data, (ii) provides very accurate results for simple and complex fractured domains, (iii) is insensitive to spatial discretization, and (iv) is computationally very efficient. The method is therefore suitable to discretize fracture networks for flow and transport simulations in fractured porous media.
