Data for: DDFS3D: a set of open-source codes leveraging hybrid 3D displacement discontinuity method and fictitious stress method to simulate fractures

Supplementary material for the paper entitled: "DDFS3D: a set of open-source codes leveraging hybrid 3D displacement discontinuity method and fictitious stress method to simulate fractures". This supplementary material contains three components: a) the user manual of DDFS3D (S1), b) source codes of DDFS3D (S2), and c) three numerical examples to verify the triangular element (S3). The input and output files of the numerical examples presented in the master paper and supplementary file S3 are included in the respective folders of supplementary file S2. We highly encourage users to explore secondary development based on DDFS3D, which can enlarge the DDFS community and advance the application of DDFS.题为《DDFS3D：一套融合混合三维不连续位移法与虚拟应力法以模拟断裂的开源代码》的论文的补充材料。本补充材料包含三部分内容：a) DDFS3D用户手册（S1）；b) DDFS3D源代码（S2）；c) 用于验证三角单元的三个数值算例（S3）。正刊及补充材料S3中提及的数值算例的输入输出文件，均收纳于补充材料S2对应的子文件夹中。我们诚挚鼓励用户基于DDFS3D开展二次开发，此举将有助于壮大DDFS社区并推动其应用拓展。
