离散裂缝网络模拟需要大量的计算，并且通常需要花费大量的时间来构建和配置。本文结合裂缝孔径分布的确定性和随机信息，介绍了建立非均匀裂缝网络三维有限元模型的技术，用于模拟流动和示踪剂输送。复杂的相交裂缝对几何模型设计、网格质量要求和属性分配提出了挑战。在综合和整体建模方法方面，包括应用数值和分析模拟技术，在软件工程中实施了新的面向对象概念，以确保一个资源丰富和可行的软件环境。
Discrete fracture network simulations are computationally intensive and usually time-consuming to construct and configure. This paper presents a case study with techniques for building a 3D finite element model of an inhomogeneous fracture network for modelling flow and tracer transport, combining deterministic and stochastic information on fracture aperture distributions. The complex intersected fractures represent a challenge for geometrical model design, mesh quality requirements and property allocations. For the integrated and holistic modelling approach, including the application of numerical and analytical simulation techniques, new object-oriented concepts in software engineering are implemented to ensure a resourceful and practicable software environment.
