An energy- and helicity-conserving enriched galerkin method for the incompressible Navier-Stokes equations
Siyuan Tong, Qilong Zhai, Qian Zhang +1
We develop an enriched Galerkin (EG) method for the incompressible Navier-Stokes equations that conserves both kinetic energy and helicity in the inviscid limit without introducing…

A pressure-robust and parameter-free enriched Galerkin method for the Navier-Stokes equations of rotational form
Shuai Su, Xiurong Yan, Qian Zhang
In this paper, we develop a novel enriched Galerkin (EG) method for the steady incompressible Navier-Stokes equations in rotational form, which is both pressure-robust and paramete…

A novel parameter-free and locking-free enriched Galerkin method for linear elasticity
Shuai Su, Xiurong Yan, Qian Zhang
We propose a novel parameter-free and locking-free enriched Galerkin (EG) method for solving the linear elasticity problem in both two and three dimensions. Unlike existing locking…
