Abstract In hydromechanical applications, Darcy, Brinkman, Forchheimer and Richards
equations play a central role when porous media flow under saturated and unsaturated …

A fully coupled dynamic model is presented in this paper by considering the effect of matric
suction, varying parameters in connection with saturation, stratification and transverse …

FreeHyTE is a public, open-source and user-friendly software for the solution of initial
boundary value problems using hybrid-Trefftz finite elements. FreeHyTE is designed to be …

Bender elements are shear wave transducers, widely used for the experimental
identification of the small-strain shear moduli of geomaterials. They offer good coupling with …

A novel, local and frequency-dependent absorbing boundary condition for unsaturated
porous media is presented. It relates the far-field tractions and displacements produced by a …

We present a new model updating technique for the automatic calculation of the small strain
shear modulus of geomaterials, based on bender element experiments. The technique …

A new dual reciprocity‐type approach to approximating the solution of non‐homogeneous
hyperbolic boundary value problems is presented in this paper. Typical variants of the dual …

A new hybrid-Trefftz finite element for the solution of transient, non-homogeneous parabolic
problems is formulated. The governing equations are first discretized in time and reduced to …

Hybrid-Trefftz finite elements combine favourable features of the Finite and Boundary
Element methods. The domain of the problem is divided into finite elements, where the …
