Witryna1 gru 2024 · 1. Introduction. Immersed finite element methods – such as, e.g., the finite cell method (FCM) [1], CutFEM [2] and immersogeometric analysis [3], [4], [5] – have been demonstrated to be suitable for computational problems for which the performance of mesh-fitting finite element methods is impeded by complications in the meshing … Witryna19 sty 2024 · The resulting topology-preserving immersed isogeometric analysis is demonstrated using prototypical test cases in two and three dimensions, considering …
WitrynaTrimming is a common operation in computer aided design and, in its simplest formulation, consists in removing superfluous parts from a geometric entity described via splines (a spline patch). After trimming, the geometric description of the patch remains unchanged, but the underlying mesh is unfitted with the physical object.
