An algorithmic approach to direct spline products: procedures and computational aspects
Francesco Patrizi, Alessandra Sestini
We introduce an efficient algorithmic procedure for implementing the direct formula that represents the product of splines in the B-spline basis. We first demonstrate the relevance…
A Smoothly Varying Quadrature Approach for 3D IgA-BEM Discretizations: Application to Stokes Flow Simulations
Cesare Bracco, Francesco Patrizi, Alessandra Sestini
We introduce a novel quadrature strategy for Isogeometric Analysis (IgA) boundary element discretizations, specifically tailored to collocation methods. Thanks to the dimensionalit…
A broken-FEEC framework for structure-preserving discretizations of polar domains with tensor-product splines
Yaman Güçlü, Francesco Patrizi, Martin Campos Pinto
We propose a novel projection-based approach to derive structure-preserving Finite Element Exterior Calculus (FEEC) discretizations using standard tensor-product splines on domains…
Local spline refinement driven by fault jump estimates for scattered data approximation
Cesare Bracco, Carlotta Giannelli, Francesco Patrizi +1
We present new fault jump estimates to guide local refinement in surface approximation schemes with adaptive spline constructions. The proposed approach is based on the idea that,…
