Abstract: Abstract An error-driven grid refinement technique is introduced for 2-D reliable crack analysis by an enriched natural element method (more exactly, Petrov-Galerkin natural element method). A quasi-exact solution for a posteriori error estimation was obtained… read more here.

Abstract: This study focuses on grid refinement techniques for the direct simulation of aeroacoustics, when using weakly compressible lattice Boltzmann models, such as the D3Q19 athermal velocity set. When it comes to direct noise computation, very… read more here.
