Automatic Adaptive and Targeted Localized Refinement in Transient Structural Dynamic Simulations Using the Multiresolution Finite Wavelet Domain Method

International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT The multiresolution finite wavelet domain method has been meticulously studied in numerous wave propagation simulations, showing excellent convergence properties and very fast computing times. The multiresolution procedure always starts with the coarse solution, and then finer solutions can be superimposed on the coarse solution until ...

A Space-Time Discontinuous Galerkin Trefftz Method for time dependent Maxwell's equations

, 2014
We consider the discretization of electromagnetic wave propagation problems by a discontinuous Galerkin Method based on Trefftz polynomials. This method fits into an abstract framework for space-time discontinuous Galerkin methods for which we can prove ...

Influence of Blood Rheology on Hemodialysis Efficiency via Computational Simulation

Chemical Engineering &Technology, Volume 49, Issue 1, January 2026.
This study presents a CFD framework for hemodialysis that explicitly incorporates cholesterol‐dependent non‐Newtonian blood rheology. By coupling mass transport with the mHAWB model, the work quantifies how rheology alters creatinine removal and optimal operating conditions. ABSTRACT This work presents a computational study of hemodialysis in cocurrent

Meshless IEFGM‐Based Numerical Modeling of Grounding Systems With Counterpoise Wires

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 39, Issue 1, January/February 2026.
ABSTRACT This paper presents a comprehensive numerical analysis of a counterpoise grounding wire subjected to low‐frequency surge currents, employing the Interpolating Element‐Free Galerkin Method (IEFGM). The analysis involves significant challenges arising from the high ratio between the conductor length and its radius—which demands fine spatial ...

Space-time discontinuous Galerkin method for the compressible Navier-Stokes equations on deforming meshes [PDF]

, 2006
An overview is given of a space-time discontinuous Galerkin finite element method for the compressible Navier-Stokes equations. This method is well suited for problems with moving (free) boundaries which require the use of deforming elements. In addition,

On the Stability Barrier of Hermite Type Discretizations of Advection Equations

Numerical Methods for Partial Differential Equations, Volume 42, Issue 1, January 2026.
ABSTRACT We establish a stability barrier for a class of high‐order Hermite‐type discretization of 1D advection equations underlying the hybrid‐variable (HV) and active flux (AF) methods. These methods approximate both cell averages and nodal solutions and evolve them in time simultaneously.

Dynamic Simulation of Distribution Networks Using Multi-stage Discontinuous Galerkin Method

CSEE Journal of Power and Energy Systems
Dynamic simulation plays a fundamental role in security evaluation of distribution networks (DNs). However, the strong stiffness and non-linearity of distributed generation (DG) models in DNs bring about burdensome computation and noteworthy instability ...
