Critical time-step size analysis and mass scaling by ghost-penalty for immersogeometric explicit dynamics
Stein K. F. Stoter, Sai C. Divi, E. Harald van Brummelen +3
In this article, we study the effect of small-cut elements on the critical time-step size in an immersogeometric context. We analyze different formulations for second-order (membra…
Hierarchical multigrid approaches for the finite cell method on uniform and multi-level hp-refined grids
John Jomo, Oguz Oztoprak, Frits de Prenter +3
This contribution presents a hierarchical multigrid approach for the solution of large-scale finite cell problems on both uniform grids and multi-level hp-discretizations. The prop…
Unification of variational multiscale analysis and Nitsche's method, and a resulting boundary layer fine-scale model
Stein K. F. Stoter, Marco F. P. ten Eikelder, Frits de Prenter +4
We show that in the variational multiscale framework, the weak enforcement of essential boundary conditions via Nitsche's method corresponds directly to a particular choice of proj…
