A Stable Mimetic Finite-Difference Method for Convection-Dominated Diffusion Equations

James H. Adler, Casey Cavanaugh, Xiaozhe Hu +2

Convection-diffusion equations arise in a variety of applications such as particle transport, electromagnetics, and magnetohydrodynamics. Simulation of the convection-dominated reg…

Efficient optimization-based quadrature for variational discretization of nonlocal problems

Marco Pasetto, Zhaoxiang Shen, Marta D'Elia +3

Casting nonlocal problems in variational form and discretizing them with the finite element (FE) method facilitates the use of nonlocal vector calculus to prove well-posedeness, co…

Entropy stable discontinuous Galerkin methods for the shallow water equations with subcell positivity preservation

Xinhui Wu, Nathaniel Trask, Jesse Chan

High order schemes are known to be unstable in the presence of shock discontinuities or under-resolved solution features, and have traditionally required additional filtering, limi…

A General-Purpose, Inelastic, Rotation-Free Kirchhoff-Love Shell Formulation for Peridynamics

Masoud Behzadinasab, Mert Alaydin, Nathaniel Trask +1

We present a comprehensive rotation-free Kirchhoff-Love (KL) shell formulation for peridynamics (PD) that is capable of modeling large elasto-plastic deformations and fracture in t…
