An Adaptive Method for Flow Simulation in Three-Dimensional Heterogeneous Discrete Fracture Networks
14 years 11 months ago
Natural fractured media are highly unpredictable because of existing complex structures at the fracture and at the network levels. Fractures are by themselves heterogeneous objects...

This video describes a new type of 3D curves, which generalizes the family of 2D Euler spirals. They are defined as the curves having both their curvature and their torsion evolv...
