Solving thermoelasticity problems by means of Trefftz functions
Computer Assisted Methods in Engineering and Science, 2017 The paper presents a new method of approximate solving of the two- and three-dimensional thermoelasticity problems in a finite body. The method presented here can be used for solving direct and inverse problems as well.

Computer Assisted Methods in Engineering and Science, 2023 This paper describes the application of Trefftz method to the steady-state heat conduction problem on the functionally gradient materials. Since the governing equation is expressed as the non-linear Poisson equation, it is difficult to apply the ...

Amplitude-based Generalized Plane Waves: new Quasi-Trefftz functions for scalar equations in 2D
CoRR, 2020 Generalized Plane Waves (GPWs) were introduced to take advantage of Trefftz methods for problems modeled by variable coefficient equations. Despite the fact that GPWs do not satisfy the Trefftz property, i.e. they are not exact solutions to the governing equation, they instead satisfy a quasi-Trefftz property: they are only approximate solutions.

Trefftz functions in FEM, BEM and meshless methods
Computer Assisted Methods in Engineering and Science, 2022 The paper contains three different multi-domain formulations using Trefftz (T -) displacement approximation/ interpolation, namely the hybrid-displacement FEM, reciprocity based FEM (multi-domain BEM) and the Boundary Meshless Method (BMM) for a single ...
