The numerical data in this repository pertains to the simulation results of quartz cementation in polycrystalline sandstones. The simulations were performed using the software package named "Pace3D version 2.5.1". The software license can be purchased at Steinbeis Network (www.steinbeis.de) in the management of Britta Nestler and Michael Selzer under the subject area ‘Material Simulation and Process Optimization’. The data is organized, the way it appears in the figures in the manuscript. Thus, the folders are named according to the figure number in the manuscript. Each folder contains a separate ReadMe.dat file, which contains all the information regarding the data present in that folder. For the sake of convenience, the simulation data that comprises the pictures is converted to .stl and .vtk format, for visualization using open source software packages like Paraview and MeshLab. The original complete output data is in the formats (e.g. *.phiindex.p3s, *.fluiddynamics_velocity.p3v etc.) which can be visualized using the in-house visualization tools GLviewer and XSimview. The data presented in plots is extracted from the simulation output using the post-processing tool chain of "Pace3D".
