Trefftz functions as basic functions of FEM in application to solution of inverse heat conduction problem

Computer Assisted Methods in Engineering and Science, 2023
The work presents the application of heat polynomials for solving an inverse problem. The heat polynomials form the Trefftz Method for non-stationary heat conduction problem. They have been used as base functions in Finite Element Method. Application of

T -functions for 2-D creeping flow on domains with circular cylinders, corners, and possessing symmetry

Computer Assisted Methods in Engineering and Science, 2023
The purpose of the paper is to propose of a way of constructing trial functions for the indirect Trefftz method as applied to 2-D creeping (Stokes) flow problems.

Three types of quasi-Trefftz functions for the 3D convected Helmholtz equation: construction and approximation properties

IMA Journal of Numerical Analysis
Abstract Trefftz methods are numerical methods for the approximation of solutions to boundary and/or initial value problems. They are Galerkin methods with particular test and trial functions, which solve locally the governing partial differential equation (PDE). This property is called the Trefftz property.

Trefftz function for solving a quasi-static inverse problem of thermal stresses

Computer Assisted Methods in Engineering and Science, 2017
The problem of thermal stresses in a hollow cylinder is considered. The problem is two-dimensional and the cross-section of the hollow cylinder is approximated as a long and thin rectangle as the ratio of the inner and outer radiuses is close to one. On
