WitrynaPhD position on addressing certain challenges of immersed isogeometric analysis in the context of scan-based simulations. Over the last four years, the potential of immersed isogeometric analysis has become obvious to me. Through this dissertation, I have been lucky enough to be able to cover a few aspects of the field with Clemens … Witryna28 lut 2024 · On the other hand, immersed boundary methods (IBM) have been developed to avoid the difficulty of meshing complex domains. In this regard, immersed boundary conformal isogeometric analysis (IBC-IGA) combines the efficacy of IBM with the accuracy of IGA by using immersed discretizations with boundary-conformal …

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. We discuss … WitrynaIn comparison to boundary- tting isogeometric analysis, the immersed isogeometric analysis strategy requires consideration of three (categories of) non-standard computational aspects. First, the geometry of elements that intersect with the boundary of the computational domain must be resolved by a dedicated integration procedure; see … how do i put a lock oin my doory
