Recent developments in T-Trefftz and F-Trefftz Finite Element Methods

This paper presents an overview of both T-Trefftz and F-Trefftz finite element methods (FEM) and its application in various engineering problems. Recent developments on the T-Trefftz finite element formulation of nonlinear problems of minimal surface, F-Trefftz methods for composite, skin tissue, and functionally graded materials are described ...

Trefftz method: Fitting boundary conditions

International Journal for Numerical Methods in Engineering, 1987
AbstractThe paper presents various ways of fitting the boundary conditions in the T‐complete functions method. The authors point out the distinct advantages of the orthogonal collocation in comparison to the equidistant collocation and the integral fit.

Quasi Trefftz Spectral Method for Stokes Problem

Mathematical Models and Methods in Applied Sciences, 1997
A new numerical Quasi Trefftz Spectral Method (QTSM) which was earlier suggested for solving boundary value and initial value problems with elliptic operators is applied to linear stationary hydrodynamic problems. The primitive variables [Formula: see text] are used.

Coupling FEM with a Multiple-Subdomain Trefftz Method

Journal of Scientific Computing, 2020
We consider 2D electromagnetic scattering at bounded objects consisting of different, possibly inhomogeneous materials. We propose and compare three approaches to couple the finite element method (FEM) in a meshed domain encompassing material inhomogeneities and the multiple multipole program (MMP) in the unbounded complement.
