Abstract: Provided are a method and a system for randomly generating a porous medium model. The method includes following steps: setting a porosity, resolution and a size of a pre-generated porous medium model; initializing the porous medium model and generating position information of particles; extracting particle profile edges; obtaining filled particles; carrying out a collision detection on the filled particles and preset particles, and determining effectiveness of a particle generation position; presetting a cyclic pop-up condition, and if a judgment result meets the cyclic pop-up condition, continuing; otherwise, updating Fourier parameters; adding a particle configuration meeting the cyclic pop-up condition to a model generation area, and storing parameters; determining whether the generated model meets preset generation requirements, and if so, outputting a porous medium model.
