Matlab files used to produce the figures in the publication: The onset of depletion-induced seismicity in slip-weakening faults with interacting peaked shear stresses: Uenishi and Rice extended.

This dataset contains the MATLAB code <em>Induced Fault Slip (IFS)</em> version 3.0 to simulate the depletion-induced growth of slip patches in an inclined displaced fault with constant or slip-weakening friction. It employs a semi-analytical approach with the aid of expansions in Chebyshev polynomials and Gauss-Chebyshev quadrature. It has been used to produce most figures in the following two publications:<br>[1] Jansen, J.D. and Meulenbroek, B.J., 2025: The onset of depletion-induced seismicity in slip-weakening faults with interacting peaked shear stresses: Uenishi and Rice extended. Accepted for publication in <em>Journal of Geophysical Research – Solid Earth.</em><br> [2] Meulenbroek, B.J. and Jansen, J.D., 2024: The use of Cauchy-type singular integrals over neighboring intervals to compute induced slip in displaced faults. <em>International Journal of Solids and Structures </em><strong>300</strong>, 112922. https://doi.org/10.1016/j.ijsolstr.2024.112922 The files have been prepared for MATLAB R2021b. This collection contains three main files: <em>ifs.main.m</em>, <em>ifs_main_UandR_convergence.m</em> and <em>ifs_main_nucleation.m</em>. Main file <em>ifs_main.m</em> is the most important file which drives most of the computations and produces most of the figures. The other two main files (<em>ifs_main_UandR_convergence.m</em> and <em>ifs_main_nucleation.m</em>) are dedicated files to produce Figures 6, 7, 10 and D.1 of reference [1]. Within <em>ifs_main.m</em>, there is an option to select three input files:01 = Example – This file creates most of the plots for reference [1] and Figure 4 for reference [2].02 = Depletion in a reservoir with a symmetric displaced vertical fault – This file creates plots that are not used in the publications.04 = Example with small and large relative fault throws - This file creates several plots for reference [1].06 = Nucleation as function of fault throw - This input file is only relevant for main file ifs_main_nucleation.m to create Figure 10 for reference [1]. <em>ifs_main_nucleation.m</em> has an option to produce new results (time consuming – 1 to 2 hours) or to recreate results from data stored in directory <em>IFS output files</em> (see the setting of <em>flag_from_file</em>). To run these files, change the path in "admin.path_out" (see line 62 in <em>ifs_main.m</em>, and line 50 in <em>ifs_main_nucleation.m</em>).

本数据集包含用于模拟倾斜位移断层中油藏枯竭引发的滑移斑块生长的MATLAB代码**诱导断层滑移（Induced Fault Slip, IFS）** 3.0版本，该代码支持恒定摩擦与滑移弱化摩擦两种条件。其采用半解析方法，借助切比雪夫多项式（Chebyshev polynomials）展开与高斯-切比雪夫求积法（Gauss-Chebyshev quadrature）完成计算。

该代码已用于生成以下两篇学术论文中的绝大多数图表：

本数据集的所有文件均适配MATLAB R2021b版本。本合集包含三个核心文件：`ifs_main.m`、`ifs_main_UandR_convergence.m`与`ifs_main_nucleation.m`。其中主文件`ifs_main.m`为核心计算文件，可驱动绝大多数计算流程并生成绝大多数图表。其余两个专用文件（`ifs_main_UandR_convergence.m`与`ifs_main_nucleation.m`）分别用于生成参考文献[1]中的图6、图7、图10与附录D.1。

在`ifs_main.m`中，提供了四种输入文件选择选项：
01 = 示例文件：用于生成参考文献[1]的绝大多数绘图结果，以及参考文献[2]的图4。
02 = 对称位移垂直油藏断层枯竭模拟：用于生成未在上述两篇论文中使用的绘图结果。
04 = 含大小相对断层落差的示例：用于生成参考文献[1]的多张绘图结果。
06 = 断层落差相关成核作用：该输入文件仅适用于主文件`ifs_main_nucleation.m`，用于生成参考文献[1]的图10。

`ifs_main_nucleation.m`支持两种运行模式：生成全新计算结果（耗时1~2小时），或从`IFS output files（IFS输出文件）`目录下存储的已有数据中复现计算结果（可通过设置`flag_from_file`参数实现）。

运行这些文件时，需修改`admin.path_out`中的文件路径（详见`ifs_main.m`第62行，以及`ifs_main_nucleation.m`第50行）。
