A posteriori analysis of operator decomposition on interface problems
… effects of operator decomposition on interface problems. Operator decomposition offers an attractive solution strategy for multi-physics and multi-scale problems. This technique allows previously defined component codes optimized for single physics problems to be reused in an iterative manner to …

A three dimensional generalized finite element method for thin fibers embedded in a continuum
… mechanisms, while simultaneously accounting for multi-scale interactions would undermine the feasibility of available FEM for such models. This research project formulates and implements a multi-scale Generalized Finite Element Method (GFEM) using global-local enrichment functions (GFEM^{gl}) to …

Analysis of Three-Dimensional Fracture Mechanics Problems: A Non-Intrusive Approach Using ABAQUS and a Generalized Finite Element Method
… global (structural) and local (crack) scale problems. In the approach presented here, an initial global scale problem is solved by a commercial finite element analysis software like Abaqus, local problems containing 3-D fractures are solved by an hp-adaptive GFEM software and an …

Three-dimensional multi-scale hydraulic fracturing simulation in heterogeneous material using Dual Lattice Model
Hydraulic fracturing is a multi-physics multi-scale problem related to natural processes such as the formation of dikes. It also has wide engineering applications such as extraction of unconventional resources, enhanced geothermal energy and carbon capture and storage. Current simulators are highly …

Chemical Looping Combustion: A Multi-Scale Analysis
… within an electricity system represents a multi-scale problem, ranging from the behaviour of single particles of oxygen carrier within a reactor to how a CLC-based power plant would perform in an electricity grid. To date, these scales have been studied in isolation, with little regard for …
