DGM-FD: A Finite Difference Scheme Based on the Discontinuous Galerkin Method
… of a method, efficiency can be assessed by convergence rates and effective adaptability to different mesh structures. Finite difference and finite element methods are commonly used numerical schemes in CAA. Finite difference methods have the advantages of ease of use as well as high order …

High-order retractions for reduced-order modeling and uncertainty quantification
… grows just as fast. As a consequence, reduced-order modeling has become an essential technique in the computational scientist's toolbox. By reducing the dimensionality of a system, we are able to obtain approximate solutions to otherwise intractable problems. And because the methodology we …

High-order hybrid methods using Green's functions and finite elements
… method for N-body calculations and a new high-order method for elliptic interface problems on non-conforming volume meshes. First, the FE-based particle-particle--particle-mesh (FE-P3M) method for N-body problems is introduced. P3M methods are designed to compute quantities (e.g. …
