WebOct 8, 2024 · This paper presents the isogeometric least-squares collocation (IGA-L) method, which determines the numerical solution by making the approximate differential operator fit the real differential operator in a least-squares sense. The number of collocation points employed in IGA-L can be larger than that of the unknowns.

Introduction. Isogeometric analysis has been introduced by the seminal paper [1] as an extension of the classical finite element method. It is based on the idea of using the functions that are adopted for the geometry parametrization in computer aided design also to represent the numerical solution of the PDE of interest. WebAgainst this background, we develop Floating Isogeometric Analysis (FLIGA) which emerges from the transfer of meshless core concepts to mesh-based IGA. This novel approach resolves the mesh-distortion problem along one curved direction of the physical mesh, which we term the characteristic direction. At the same time the approach … oramorph and codeine
