A practical algorithm to minimize the overall error in FEM computations
Jie Liu, Henk M. Schuttelaars, Matthias Möller
Using the standard finite element method (FEM) to solve general partial differential equations, the round-off error is found to be proportional to , with the num…

Three Numerical Eigensolvers for 3-D Cavity Resonators Filled With Anisotropic and Nonconductive Media
Wei Jiang, Jie Liu
This paper mainly investigates the classic resonant cavity problem with anisotropic and nonconductive media, which is a linear vector Maxwell's eigenvalue problem. The finite eleme…
