Domain-decomposition least-squares Petrov–Galerkin (DD-LSPG) nonlinear model reduction

This work proposes a domain-decomposition approach for the least-squares Petrov–Galerkin (LSPG) reduced-order model. The DD-LSPG method enables reduced-order models to be constructed independently on subdomains of the computational domain, which …

The network uncertainty quantification method for propagating uncertainties in component-based systems

This work introduces the network uncertainty quantification (NetUQ) method for performing uncertainty propagation in systems composed of interconnected components. The method assumes the existence of a collection of components, each of which is …
