This dataset corresponds to the model made from the EGS project of Basel (2006, Switzerland). The model solves the coupled hydro-mechanical problem for a 2D fault network on a surface of 1 km2, located at 4630-m deep coinciding with the injection depth in the crystalline basement at Basel. A set of faults is embedded in a rock matrix, with the fault network derived from the induced seismicity that was monitored in the range of 3750 and 4750-m deep. The maximum principal stress S_Hmax is aligned with y-axis (S_Hmax=160 MPa, S_hmin=84 MPa, S_v=115 MPa). The hydrostatic pressure is set at 45 MPa following a hydrostatic profile and the temperature at the depth of the reservoir is set at 190°C. Stimulation parameters are inputs as wellhead pressure based on the injection strategy from Häring et al. (2008). The injection fluid is water. This dataset includes the following files: - “ .gid” is the Code_Bright file with the model of Basel. The file “_gen.dat” contains the input data of the model (including material properties, initial and boundary conditions and the time intervals). The file “_gri.dat” includes the information on the mesh. The “root.dat” includes the name of the model. To run simulations, execute the Code_Bright executable “Cb_2020_21.exe” in a folder that contains the three input files and the executable.  V13_C_elastic.gid corresponds to the model in which the faults have an elastic behavior.  V13_C_F245_D5_P1.gid corresponds to the model in which the faults have an viscoplastic behavior, and fault C has a slip weakening of 5°. - “Deichmann_et_al_2014_cluster.txt” is the file proposed by Deichmann et al. (2014). Seismic events are sorted by clusters, in function of the location and focal mechanisms., Peer reviewed
