The Wessex Institute of Technology has been convening conferences on the Boundary Element Method since 1978. The now-annual conference series is recognised internationally as the premiere forum for sharing the latest advances on the boundary element method and other meshless techniques and their applications, which continue to evolve and grow in importance. The papers presented at the latest conference, contained in this volume, cover topics such as: Advances in Solid Mechanics; Fluid Flow Applications; Computational Methods; Advanced Formulations; Advanced Meshless and Mesh reduction Methods.

Contents Section 1: Advances in solid mechanics Probabilistic fatigue crack growth using BEM and reliability algorithms; Modification of Gauss-Chebyshev quadrature for modelling of crack growth in the field of residual stresses; A tangential differential operator applied to stress and traction boundary integral equations for plate bending including the shear deformation effect; The BEM for buckling analysis of viscoelastic plates modelled with fractional derivatives Section 2: Fluid flow applications BEM simulation of transient fluid flow phenomena; Devised numerical criteria for calculating the density diffusion in a water reservoir; Application of the boundary element method to 2D and 3D bubble dynamics; Calculation of propeller's load noise using LES and BEM numerical acoustics coupling methods; URANS and LES methodology for two-dimensional natural convection in a differentially heated cavity by BEM; BEM simulations of diffraction-optimized noise barriers Section 3: Computational methods A shape sensitivity analysis approach based on the boundary element method; An efficient boundary element modeling of the time domain integral equations for thin wires radiating in a presence of a lossy media; Stability issues in 3D BEM formulations for transient elastodynamics; A multi-domain boundary element analysis technique based on a row elimination-back-substitution method for solving large-scale engineering problems; A boundary element formulation for axi-symmetric problems in poro-elasticity Section 4: Advanced formulations The expedite boundary element method; A fundamental solution based FE model for thermal analysis of nanocomposites; On STEM of tectonic stress fields in tsunami regions Section 5: Advanced meshless and mesh reduction methods Time integrations in solution of diffusion problems by local integral equations and moving least squares approximation; The MFS for the detection of inner boundaries in linear elasticity; IRBFN-based multiscale solution of a model 1D elliptic equation; A meshless solution of two dimensional density-driven groundwater flow; Evenly spaced data points and radial basis functions; An efficient implementation of the radial basis integral equation method; Forced vibrations of tanks partially filled with liquid under seismic load; Solving heat transfer in a timber beam exposed to fire with methods based on radial basis functions (RBFs); Moving least square - one dimensional integrated radial basis function networks for time dependent problems; The radial basis integral equation method for 2D Helmholtz problems; Meshless computation for partial differential equations of fractional order
