*Simulating the Coupling of High-Frequency Transients to Power Grid Transmission Lines

The coupling of an electromagnetic wave to a power grid transmission line is simulated using the RF Module and the COMSOL Multiphysics® software. The problem is relevant to understanding disruptions to the power grid from intense electromagnetic disturbances, such as solar events and electromagnetic pulses (EMPs). Several models are simulated for various transmission line configurations above various local earth conditions with different permittivity and conductivity parameters. Ultimately, the coupling of these fields to transmission lines may induce voltages and currents in large substation distribution transformers. A comparison of COMSOL Multiphysics® results with simplified transmission line models is made and enhancements to these simplified models are made based on full-wave electromagnetic simulations using COMSOL Multiphysics®.

*This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.

Multiphysics Modeling for Equipment Performance Analysis and Control Design

SC Solutions provides modeling, analysis, and control system design solutions for semiconductor and advanced material manufacturing, energy, and aerospace industries. SC is a Certified Consultant for the COMSOL Multiphysics® software and has used COMSOL Multiphysics® for the past fifteen years in its modeling activities. SC Solutions’ controller and system optimization products have been proven in the field for over a decade. We refer to this technology as model-based control (MBC) design. We use physics-based models for engineering analysis, design optimization, and the development of high-performance controllers; e.g., for real-time feedback control design of wafer processing in semiconductor and LED chip manufacturing equipment used in fabs globally. The high-order FEM model developed in COMSOL® is used in the development of next-generation systems right from the design stage, which allows the assessment of candidate designs and system optimization before “cutting metal”. Additionally, we have used simulation models for virtual sensing, fault diagnostics from field data, and equipment health monitoring.

In this talk, we describe a set of applications where SC has used COMSOL Multiphysics® for multiphysics modeling. These models span the transport of heat, fluids and chemical species, structural mechanics, acoustics, and electrochemistry. In each case, the models were either validated with experimental data or a simpler version of the model was verified with analytical results.

Use of the COMSOL Server License to Simulate Next-Generation Synchrotron Light Sources

Next-generation synchrotron light sources are creating orders-of-magnitude brighter X-rays by reducing horizontal dispersion. This requires the bending magnet pole tips to be closer to the electron beam axis, which in turn requires smaller vacuum chambers. The resultant design challenges are dictated by complex and coupled physical phenomena, including high thermal stresses, photon-stimulated desorption, and electromagnetic wakefields. The Application Builder in COMSOL Multiphysics® enables the creation of browser-based GUIs, which enable scientists and engineers to study this complicated problem domain without becoming an expert user of the COMSOL® software. With a relatively inexpensive COMSOL Server License, these GUIs can be executed on a cloud-based server, with many processors and all of the required RAM for complex simulations. This approach extends the power of COMSOL Multiphysics® to collaborators, customers, students, etc. We present two such GUIs: 1) The emission of synchrotron radiation and resultant thermal stress on vacuum chamber walls that are downstream of dipole bending sections, and 2) accurate thermal analysis and optimized mechanical bending correction for high-heat-load beamline mirrors. The various challenges of creating the underlying FEA models and the methods used to overcome them will be discussed. Both examples are relevant to the Advanced Photon Source upgrade (APS-U) under construction at Argonne National Laboratory.

11:15am

Learn how to convert a model into a custom app using the Application Builder, which is included in the COMSOL Multiphysics® software. You can upload your apps to a COMSOL Server™ installation to access and run the apps from anywhere within your organization.
