Finite Elements in Analysis and Design, 2023 This work introduces “generalized meshes”, a type of meshes suited for the discretization of partial differential equations in non-regular geometries. Generalized meshes extend regular simplicial meshes by allowing for overlapping elements and more flexible adjacency relations.

Hydraulic fracture propagation in naturally fractured reservoirs: Complex fracture or fracture networks [PDF]
Journal of Natural Gas Science and Engineering, 2019 Understanding the behavior of fluid-driven hydraulic fracture in naturally fractured reservoirs is crucial in the development of geothermal energy and unconventional reservoirs. This study presents a fully-coupled numerical model to investigate hydraulic propagation in naturally fractured reservoirs, along with a comprehensive discussion on field ...
