We published a first preprint at arXiv
on our research on Isogeometric BEM for Superconducting Cavities (DFG SCHO 1562/3-1
and KU 1553/4-1
). In cooperation with the Computational Mathematics
group in Basel we discuss the usage of higher order B-splines in view of regularity requirements, convergence of the solution within the domain and multipole compression techniques. Continue reading →

Our paper on Waveform Relaxation for the Computational Homogenization of Multiscale Magnetoquasistatic Problems (Innocent Niyonzima, Christophe Geuzaine, Sebastian Schöps) has been accepted by JCP
This paper proposes the application of the waveform relaxation method to the homogenization of multiscale magnetoquasistatic problems. In the monolithic heterogeneous multiscale method, the nonlinear macroscale problem is solved using the Newton–Raphson scheme. The resolution of many mesoscale problems per Gauss point allows to compute the homogenized constitutive law and its derivative by finite differences. In the proposed approach, the macroscale problem and the mesoscale problems are weakly coupled and solved separately using the finite element method on time intervals for several waveform relaxation iterations. The exchange of information between both problems is still carried out using the heterogeneous multiscale method. However, the partial derivatives can now be evaluated exactly by solving only one mesoscale problem per Gauss point. Continue reading →
The graphical user interface of Octave 4.0 can only be compiled with Qt4. Homebrew is dropping 4.x support and moving towards 5.x. Several Octave dependencies have already been updated (e.g. Qscintilla2, see e.g. this issue. However, the upcoming Octave 4.2 (release is scheduled for September 2016) will have full Qt5 as discussed here.
The standard installation uses the command line interface. If you need Octave with graphical user interface then this should work
brew upgrade #to get the latest qscintilla
brew install octave --with-gui --HEAD
: The post has been edited on Aug 20 since the new formula is now available in homebrew’s science repository

Prof. Dr. Sergej Rjasanow from Saarland University talks on Finite Element Method on uniform and adaptive polygonal and polyhedral meshes at 30 May 2016, 16:15–17:45; Location: S2|17-103. From the abstract
In the development of numerical methods to solve boundary value problems the requirement of flexible mesh handling gains more and more importance. The BEM-based finite element method  is one of the new promising strategies which yield conforming approximations on polygonal and polyhedral meshes, respectively. Continue reading →
According to a recent study of Prognos
Darmstadt is the city with the 9th highest potential
in Germany. In a similar study of IW Consult
Darmstadt was even number one. The reasons were similar, for example: many young and well educated inhabitants with background in mathematics, natural sciences or engineering. Wirtschaftswoche
said “Hier profitiert Darmstadt von seiner 1877 gegründeten Technischen Universität. Hinzu kommt die Sogwirkung auf High Potentials durch drei Fraunhofer-Institute und das GSI Helmholtzzentrum für Schwerionenforschung, das gerade den Bau eines gigantischen Teilchenbeschleunigers vorbereitet.
