Verification benchmarks for single-phase flow in three-dimensional fractured porous media

Flow in fractured porous media occurs the earth’s subsurface, biological tissues, and man-made materials. Fractures have a dominating influence on flow processes, last decade has seen an extensive development of models numerical methods that explicitly account for their presence. To support these developments, four benchmark cases single-phase three-dimensional are presented. The specifically designed to test methods’ capabilities handling various complexities common geometrical structures fracture networks. Based open call participation, results obtained with 17 were collected. This paper presents underlying mathematical model, overview features participating methods, performance solving cases.
