The Trefftz Boundary Method in Viscoelasticity
Computer Modeling in Engineering & Sciences, 2007 In this paper, the Trefftz method is applied to solve linear viscoelasticity problems in the time domain, using Trefftz elastic series and considering the viscoelastic components in each time domain as fictitious body forces. The direct application of the Trefftz method to elastic problems is typically constrained to those cases in which the Navier ...

Self-adaptive Trefftz procedure for harmonic problems
Computer Assisted Methods in Engineering and Science, 2023 The paper propose two adaptive algorithms based on a Trefftz method for two-dimensional Laplace equation satisfying the maximal principle. First one for given the error tolerance and an initial number of terms in the solution expansion, the algorithm ...
