Workshop on Order-Reduction Methods 2016

worm2016 The 3rd International Workshop on Order-Reduction Methods for Mechanics of Materials (WORM 2016) took place from Aug 29th – Wed, Aug 31st, 2016 in Bad Herrenalb, Germany. We presented recent results on domain decomposition and model order reduction in the context of Isogeometric analysis (IGA); title: Towards Reduced Order Modelling of Resonant Cavities for Particle Accelerators discretized by IGA; authors: Corno, de Falco and Schöps.

WORM 2014

This week I will attend the 2nd International Workshop on Order-Reduction Methods for application to Mechanics of Materials (WORM2014). Its main focus is the prediction of constitutive properties of microstructured materials using reduced order models but also related topics were welcomed. We contribute with a talk an parametrized model order reduction for Maxwell’s equations.

Kleinheubacher Tagung 2013

Slide 5: Introduction of UQNext week the Kleinheubacher Tagung 2013 of the U.R.S.I. Landesausschuss in der Bundesrepublik Deutschland e.V. will take place in Miltenbach. Scientific Program and Book of Abstracts are freely available.
  • On Tuesday, 16:40 – 17:00 Uhr (KHT2013-B.2-1) U. Römer will present our joint work on “A First Order k-th Moment Method for the Nonlinear Magnetoquasistatics Problem with Material Uncertainties”.
  • On Wednesday, 13:40-14:00 (KHT2013-B.3-1) I will present a talk about “Model Order Reduction for the Uncertainty Quantification of Voltage Insulators with Nonlinear Resistive Electric Field Grading”. This is based on research together with D. Schmidthäusler, M. Clemens. An illustration is given in the Figure to the right.

Next week I will participate at the workshop WORM 2013. It’s main scope is the prediction of the constitutive properties of microstructured materials using numerical methods is associated with a high demand in CPU time and memory. During the past two decades, order-reduction techniques have been given increased attention by both academia and industry. These methods can help to significantly reduce not only the computational time, but also the storage requirements (RAM and disk space) which are essential features when it comes to mechanics of materials. The workshop deals with this particular subdomain of model order-reduction for application to the mechanics of materials. (source: www.itm.kit.edu)
