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.
The preprint “Isogeometric Simulation of Lorentz Detuning in Superconducting Accelerator Cavities” (Corno, J.; de Falco, C.; De Gersem, H.; Schöps, S.) is online as MOX Report 31/2014. Cavities in linear accelerators suffer from eigenfrequency shifts due to mechanical deformation caused by the electromagnetic radiation pressure, a phenomenon known as Lorentz detuning. In this paper, Isogeometric Analysis is used to discretize both mechanical deformations and electromagnetic fields in a coupled multiphysics simulation approach.
Jacopo Corno was awarded a student grant from CEFC 2014 for his contribution “Isogeometric Simulation of Lorentz Detuning in Superconducting Accelerator Cavities” (joint work with Politecnico Milano, Carlo de Falco). The paper discusses the frequency shift in a superconductive cavity induced by mechanical deformation due to the electromagnetic pressure. A highly accurate solution of the coupled electromagnetic-mechanic problem is obtained by isogeometric analysis and compared to an approach based on traditional finite elements.
On Monday, November 4, at 16:15 Dr. Carlo de Falco, from the Laboratory for Modeling and Scientific Computing MOX, Politecnico di Milano and CEN Centro di Nano Medicina, Milano will talk about “IsoGeometric analysis methods for multiphysics problems”. The talk will be held in S2|17-103 (Institute TEMF at Schlossgartenstraße), see here.
