Higher order accurate mass lumping for explicit isogeometric methods based on approximate dual basis functions
Rene Hiemstra, Thi-Hoa Nguyen, Sascha Eisentrager +2
This paper introduces a mathematical framework for explicit structural dynamics, employing approximate dual functionals and rowsum mass lumping. We demonstrate that the approach ma…
An EigenValue Stabilization Technique for Immersed Boundary Finite Element Methods in Explicit Dynamics
Sascha Eisenträger, Lars Radtke, Wadhah Garhuom +4
The application of immersed boundary methods in static analyses is often impeded by poorly cut elements (small cut elements problem), leading to ill-conditioned linear systems of e…
Stability of step size control based on a posteriori error estimates
Hendrik Ranocha, Jan Giesselmann
A posteriori error estimates based on residuals can be used for reliable error control of numerical methods. Here, we consider them in the context of ordinary differential equation…
A Stabilized Circuit-Consistent Foil Conductor Model
Elias Paakkunainen, Jonas Bundschuh, Idoia Cortes Garcia +2
The magnetoquasistatic simulation of large power converters, in particular transformers, requires efficient models for their foils windings by means of homogenization techniques. I…
Grading of Triangulations Generated by Bisection
Lars Diening, Johannes Storn, Tabea Tscherpel
For triangulations generated by the adaptive bisection algorithm by Maubach and Traxler we prove existence of a regularized mesh function with grading two. This sharpens previous r…
Dimensions of exactly divergence-free finite element spaces in 3D
L. Ridgway Scott, Tabea Tscherpel
We examine the dimensions of various inf-sup stable mixed finite element spaces on tetrahedral meshes in 3D with exact divergence constraints. More precisely, we compare the standa…
