[HTML][HTML] Space–time computations of exactly time-periodic flows past hydrofoils

JE Lotz, MFP ten Eikelder, I Akkerman - Computers & Fluids, 2024 - Elsevier
The computation of periodic flows is typically conducted over multiple periods. First, a
number of periods is used to develop periodic characteristics, and afterwards statistics are …

Discontinuous Galerkin methods through the lens of variational multiscale analysis

SKF Stoter, B Cockburn, TJR Hughes… - Computer Methods in …, 2022 - Elsevier
In this article, we present a theoretical framework for integrating discontinuous Galerkin
methods in the variational multiscale paradigm. Our starting point is a projector-based …

Constraints for eliminating the Gibbs phenomenon in finite element approximation spaces

MFP ten Eikelder, SKF Stoter, Y Bazilevs… - … Models and Methods …, 2024 - World Scientific
One of the major challenges in finite element methods is the mitigation of spurious
oscillations near sharp layers and discontinuities known as the Gibbs phenomenon. In this …

A space-time framework for periodic flows with applications to hydrofoils

J Lotz, M Eikelder, I Akkerman - arxiv preprint arxiv:2211.10964, 2022 - arxiv.org
In this paper we propose a space-time framework for the computation of periodic flows. We
employ the isogeometric analysis framework to achieve higher-order smoothness in both …
