Local Element Operations for Curved Simplex Meshes

Andrew Shi, Per-Olof Persson

Mesh optimization procedures are generally a combination of node smoothing and discrete operations which affect a small number of elements to improve the quality of the overall mes…

A Face-Upwinded Spectral Element Method

Yulong Pan, Per-Olof Persson

We present a new high-order accurate discretisation on unstructured meshes of quadrilateral elements. Our Face Upwinded Spectral Element (FUSE) method uses the same node distributi…

Bidiagonal Decompositions of Vandermonde-Type Matrices of Arbitrary Rank

Jorge Delgado, Plamen Koev, Ana Marco +4

We present a method to derive new explicit expressions for bidiagonal decompositions of Vandermonde and related matrices such as the (q-, h-) Bernstein-Vandermonde ones, among othe…

High-order accurate finite difference discretisations on fully unstructured dual quadrilateral meshes

Yulong Pan, Per-Olof Persson

We present a novel approach for high-order accurate numerical differentiation on unstructured meshes of quadrilateral elements. To differentiate a given function, an auxiliary func…

Implicit shock tracking for unsteady flows by the method of lines

Andrew Shi, Per-Olof Persson, Matthew Zahr

A recently developed high-order implicit shock tracking (HOIST) framework for resolving discontinuous solutions of inviscid, steady conservation laws [41, 43] is extended to the un…

Agglomeration-Based Geometric Multigrid Solvers for Compact Discontinuous Galerkin Discretizations on Unstructured Meshes

Yulong Pan, Per-Olof Persson

We present a geometric multigrid solver for the Compact Discontinuous Galerkin method through building a hierarchy of coarser meshes using a simple agglomeration method which handl…
