New paper on MOR for nonlinear problems

Under the doi 10.3390/mca23010008 Felix Fritzen, Bernard Haasdonk, David Ryckelynck any myself have published a new paper on an algorithmic discussion of competing parametric model reduction techniques for nonlinear problems in Mathematical and Computational Applications. The Galerkin reduced basis (RB) formulation is presented, which fails at providing significant gains with respect to the computational efficiency for nonlinear problems. Renowned methods for the reduction of the computing time of nonlinear reduced order models are investigated. All approaches are applied to a simple uncertainty quantification of a planar nonlinear thermal conduction problem. The paper is free under CC BY 4.0.

Radolsav and Zeger at EPNC 2016

EPNC-2016-logo-1-2-e1455056052945Radoslav 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.

International Congress on Industrial and Applied Mathematics 2015

http://www.iciam2015.cnThe International Congress on Industrial and Applied Mathematics (ICIAM) is held every four years and from August 10 to 14, 2015, mathematicians from around the world gathered in Beijing, China for the 8th ICIAM held at the China National Convention Center inside the Beijing Olympic Green. We have been presenting works on Multirate Time-Domain Simulation of Field/Circuit Coupled PWM Controlled Devices (together with Ruth Vazquez Sabariego and Johan Gyselinck) and Modelling of TESLA Cavities’ Eccentricity with Isogeometric Analysis (Jacopo Corno with Carlo de Falco). The poster presentation of the latter work has been recorded by ICIAM TV; there is also an interview of Prof. Annalisa Buffa talking about IGA.

EU Project nanoCOPS

Am 1. November ist das EU Projekt nanoCOPS (Nanoelectronic Coupled Problems Solutions) gestartet. Führende Experten aus Industrie und Wissenschaft in Europa wollen gemeinsam neue Methoden entwickeln, die ein verbessertes und erneuertes Design von integrierten Schaltungen ermöglichen. Dafür arbeiten Spezialisten im Schaltungsentwurf, in der Halbleiterentwicklung sowie der Angewandten Mathematik in Forschung und Softwareentwicklung zusammen. Insgesamt sind zwölf Forschungsinstitutionen und Unternehmen an dem Projekt beteiligt, das von der EU im Rahmen des 7. Forschungsrahmenprogramms mit insg. 3,5 Millionen Euro für drei Jahre gefördert wird. Continue reading →
