Multi-scale problems: an improved non-intrusive algorithm that enhances FEA platforms with the generalized finite element method; An improved preconditioned conjugate gradient solver for hierarchical generalized finite element systems of equations
… software. A GFEM method that transfers small scale information to larger scales is called GFEM global-local (GFEM gl ). The process of adding GFEM gl functionality to commercial software without modifying the commercial software is called a non-intrusive algorithm. This thesis presents a new …

Spectral Integral Method and Spectral Element Method Domain Decomposition Method for Electromagnetic Field Analysis
… method (DDM) for solving inhomogeneous multi-scale problems. The proposed SIM-SEM-FEM domain decomposition algorithm can efficiently handle problems with multi-scale structures, </p><p>by using FEM to model electrically small sub-domains and using SEM to model electrically large and …

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 …

STRUCTURE-OPTIMIZED AND ORDER-PRESERVING METHODS FOR ADVECTION AND TIME STEPPING
… accurate numerical schemes that can apply to multi-physics or multi-scale problems. Motivated by the need for numerical methods with long-time accurate solutions in complex advection-dominated problems, we first address whether there are numerical schemes for constant-coefficient advection …

Reliability-based co-design and its applications to wind energy and mobile energy storage systems
… Since the proposed method adopts the idea of multi-disciplinary design optimization, it can improve the performance of autonomous systems without leveraging the difficulty in design and control for systems with uncertainties. First, the problem formulation and strategies to solve the …
