Description
We developed FracLab, a robust and powerful 3D discrete fracture network (DFN) generator for high-quality fracture networks, which can enable complex numerical simulation of coupled processes. FracLab incorporates optimized geometry trimming and enhanced rejection criteria to generate high-quality 3D DFNs, enabling robust mesh generation for both fractures and rock matrices; it also regulates minimum element size, reduces mesh element count, and improves mesh quality via full-domain geometry optimization, thereby enabling efficient 3D multiphysics simulations that can capture nonlinear geomechanical deformations, local stress variations, fracture-matrix interactions, and stress-dependent fluid flow and solute transport in densely fractured media.
