Witryna19 lip 2024 · 2 Immersed isogeometric analysis. With the aim of introducing immersed methods, the used notation, and the main ideas behind this work, let us first introduce a classical Poisson’s problem as our driving example. Even if the problem is presented in a 3D context, the same ideas are directly applicable to 2D problems. green colored mulch

Immersed isogeometric analysis

WitrynaAs an application of the developed interrogation technique the isogeometric design and analysis of lattice-skin structures is investigated. The skin is a spline surface that is usually created in a computer-aided design (CAD) system and the periodic lattice to be fitted consists of unit cells, each containing a small number of struts. WitrynaThen, we develop novel stabilization techniques based on a modification of the variational formulation, which allow us to recover well-posedness and guarantee accuracy. Optimal a priori error estimates are proven, and numerical examples confirming the theoretical results are provided. Keywords isogeometric analysis trimming …
