Exploring the Limits of Boundary Element Methods for Wave Energy Converter Hydrodynamics
… and geometric variations on BEM results through grid sensitivity analyses and comparison to experimental results. Solution verification is performed through a mesh sensitivity study using both the grid convergence index and least-squares grid convergence index methods. Solution validation was …

Extrapolation-based Discretization Error and Uncertainty Estimation in Computational Fluid Dynamics
… The asymptotic range is used to describe the convergence of a solution, where an asymptotic solution approaches the exact solution at a rate proportional to the change in mesh spacing to an exponent equal to the formal order of accuracy. A non-asymptotic solution can result in unpredictable …

Verificação de erros de discretização em problemas de radiação térmica
… empregando os estimadores de Richardson e Grid Convergence Index. Os problemas escolhidos possuem solução analítica para a maioria das variáveis analisadas, portanto é possível mostrar que as estimativas de erro são acuradas e confiáveis. Paralelamente é conduzida uma análise a priori, …
