摘要
A new method based on the combined local nonmatching grid and discrete fracture model is presented. The method is very flexible to handle matrix-matrix, fracture-fracture, and matrix-fracture connections in the context of an unstructured grid. The grid is generated at the fracture intersections, enabling accurate modeling of small control volumes between connecting fractures. Several numerical examples are presented to assess the efficiency and the accuracy of the proposed method.
