Low-Frequency Stability in Electroquasistatic Simulations

In the industrial design process of high-voltage equipment, the simulation of electroquasistatic problems is frequently applied. One example of such a case are insulators (see Figure). The simulation and optimization of the electric field, i.e. to avoid overvoltages, within these insulators are important for ensuring the safety and reliability of […]

Multiphysical Simulation and Optimisation for Magnetocaloric Refrigeration 

Refrigeration has a remarkable and often underestimated impact on global warming: globally, about 20% of the total electric energy is used for refrigeration. Additionally, conventional refrigerators work using a gas-compression cycle, and the corresponding working gas has a large global warming potential. Thus, working gas leakage leads to direct greenhouse […]

AI-TWILIGHT: AI powered Digital Twin for lighting infrastructure in the context of front-end Industry 4.0

Over the last decades, LEDs have taken over the lighting industry. Their design is a multiphysical problem, involving mechanical, optical, electrical, and thermal components and considerations. All of these domains influence the operational behavior of LEDs, with the temperature having the largest impact on the lifetime of a given product. […]

Finite Element Parasitic Extraction and Sensitivity Analysis in Industry

Parasitic extraction is a key technique in electromagnetic compatibility analysis. It enables to extract the parasitic resistances, inductances, and capacitances from a CAD model, and thereby to asses the performance of the design in a joint circuit simulation in combination with its functional circuit elements. A sensitivity analysis of the […]

Shape Optimization of an Electron Gun

S-DALINAC (Superconducting-DArmstadt-LINear-ACcelerator) is a superconducting electron accelerator at TU Darmstadt, running since 1991. It was initially constructed as a twice-recirculating accelerator with a maximum energy of 130 MeV in continuous wave (cw) operation. In 2016 it has been converted into a thrice-recirculating accelerator, see here. For the next upgrade an […]

Yield Estmation Using Surrogate Modelling in Industry

Most manufacturing processes suffer from small deviations, which may lead to rejections of some products due to malfunctioning. In this context, malfunctioning is commonly understood as violating a given performance feature specification. In order to quantify the impact of the uncertainty one defines the yield as the percentage of realizations […]

Bembel Project – A Boundary Element Method Based Engineering Library

The boundary element method (BEM) or method of moments (MoM) is a common approach for the solution of partial differential equations (PDEs) in engineering applications such as acoustic and electromagnetic scattering problems in homogeneous media. It is accepted in industry and there are many free and proprietary implementations. Bembel’s logo […]
