URSI Commission B’s International Symposium on Electromagnetic Theory (EMTS 2016) has been held from 14–18 August 2016 in Espoo, Finland. We presented in the Session of numerical time domain methods on Monday the contribution “An Application of ParaExp to Electromagnetic Wave Problems” (Melina Merkel, Innocent Niyonzima and Sebastian Schöps).

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 workbrew update brew upgrade #to get the latest qscintilla brew install octave --with-gui --HEAD

**Update**: The post has been edited on Aug 20 since the new formula is now available in homebrew’s science repository.

# Gmsh 2.13.1 and GetDP 2.9.0 in homebrew/science

Homebrew’s science repository includes now (again) the most recent versions of Gmsh 2.13.1 and GetDP 2.9

brew tap homebrew/science brew install gmsh --with-fltk brew install getdp

# Talk on the simulation of electrical machines by Lars Kielhorn

Dr. Lars Kielhorn from TailSiT GmbH, Graz (Austria) talks on 25 Jul 2016, 16:15–17:45 (room S4|10-314) in the seminar on Computational Engineering. Abstract:

*Electrical machines commonly consist of moving and stationary parts, e.g., an electric motor features a rotor and a stator. If volume based numerical schemes such as the Finite Element Method (FEM) are applied the electromagnetic simulation of such devices is a challenging task since the variation of the geometrical configuration needs to be incorporated into the numerical scheme.

The Mac package manager homebrew includes since commit 5eb3823 the latest release of GNU Octave version, i.e., 4.0.3. It features the FLTK backend by default, which should fix a lot issues with exporting images. An update of the mac binary will be uploaded soon.

# Michal Maciejewski from CERN is visiting CE

On Friday, July 1st Michal Maciejewski from CERN and Lodz University of Technology is visiting Computational Engineering at TU Darmstadt in the framework of the STEAM (“Simulation of Transient Effects in Accelerator Magnets”) cooperation, see e.g. this presentation. The aim of this project is the accurate prediction of quenches.

# Radolsav and Zeger at EPNC 2016

Radoslav Jankoski and Zeger Bontinck will present recent works on uncertainty quantification, i.e., Uncertainty Quantification of a PMSM With Dynamic Rotor Eccentricity and Shape Optimization of its Magnets and Stochastic Modeling of an Inhomogeneous Magnetic Reluctivity Using the Karhunen-loève Expansion and the Hierarchical Matrix Technique at the Symposium on Electromagnetic Phenomena in Nonlinear Circuits (EPNC) 2016 in Helsinki.

# Three presentation from CE@TUDa at ECMI 2016

The 19th European Conference on Mathematics for Industry (ECMI 2016) in Santiago is over. We organized one minisymposium and contributed three talks in the minisymposia

- Recent developments and applications of isogeometric methods
- Mathematical modeling and simulation for nanoelectronic coupled problems (nanoCOPS)
- Stochastic PDEs and uncertainty quantification with applications in engineering
