Using Rock SEM Image to Create Pore-scale Finite Element Calculation Mesh

Micro-scale numerical simulation were often used to study the deformation, flow or heat transfer mechanism of material, among the simulation, one important step is to get simulation mesh. Taking rock as an example, this paper illustrated a method of creating pore-scale finite element calculation mesh from rock Scanning Electron Microscope (SEM) image with image processing toolbox of MATLAB, Algolab Raster to Vector Conversion Toolkit and COMSOL Multiphysics software. It established a more accurate numerical model of the microscopic pore structure of rock. Simulation results demonstrate that the method is efficiency in the application of image processing and the study of microscopic pore structure.
