The aim of the present numerical study is to show that the recently developed Alternating Direction Reconstruction Immersed Boundary Method (ADR-IBM) [1] can be used for Fluid-Structure Interaction (FSI) problems and can be combined with an Actuator Line Model (ALM) and a Computer-Aided Design (CAD) interface for high-fidelity simulations of fluid ...
This study deals with the development of a numerical wire mesh screen model for the unsteady simulation of aeroacoustic configurations. Such devices are indeed of growing interest for practical applications because they potentially lead to significant noise-reduction effects. Numerical simulations including wire mesh screens are therefore of major ...

Nektar++ is an open-source framework that provides a flexible, high-performance and scalable platform for the development of solvers for partial differential equations using the high-order spectral/ element method. In particular, Nektar++ aims to overcome the complex implementation challenges that are often associated with high-order methods, there...
An approach is developed to perform explicit time domain finite element simulations of elastodynamic problems on the graphical processing unit, using Nvidiaʼs CUDA. Of critical importance for this problem is the arrangement of nodes in memory, allowing data to be loaded efficiently and minimising communication between the independently executed blo...
In many 3-D forging simulations, the master-grid method or uniform-grid method is adopted as an effect tool for hexahedral element mesh generation, because the method is robust and reliable to construct the intermediate mesh during forging simulation. However, almost equalsized element mesh is employed regardless of the local characteristics of the...

This paper introduces a three-dimensional mesh generation algorithm for domains bounded by smooth surfaces. The method combines a surface mesher with a volume mesher, both based on Delaunay refinement, to get a greedy algorithm that samples the interior and the boundary of the domain at once. The algorithm constructs provably-good meshes, it gives ...
