Casey Ladtkow, Medtronic, Boulder, CO, USA

Researchers at Medtronic studied ablation technology using multiphysics simulation to enhance physicians' abilities to plan and implement ablation procedures. Their research aimed to understand and optimize the emitting and receiving properties of ablation probes to eliminate soft tissue tumors. With the COMSOL Multiphysics® software, the research team investigated diverse aspects of the ...

Simulating Laser-Material Interactions

Manyalibo Matthews, Lawrence Livermore National Laboratory (LLNL), CA, USA

California-based Lawrence Livermore National Laboratory (LLNL) oversees the National Ignition Facility (NIF), which houses the world's largest and most energetic laser. Repeated use of this laser can damage the optics, which guide and focus the laser within the system. Manyalibo Matthews, deputy group leader in the Materials Science Division of LLNL, and his team study techniques to repair and ...

Increasing Lifespans of High-Power Electrical Systems

Samuel Hartmann, ABB Semiconductors, Switzerland

ABB Semiconductors increased the lifespan of an insulated-gate bipolar transistor (IGBT) using multiphysics simulation. IGBT modules are used in high-power electrical systems and are subjected to repeated electrical, thermal, and mechanical loading. The ABB team explored different wire-emitter configurations to see if stitched bonding techniques could extend product lifetime, and used new ...

Application Builder and COMSOL Server: A Review

William T. Vetterling, Zink Imaging, MA, USA

William Vetterling, research fellow and manager of the Image Science Laboratory at Zink Imaging, created an intuitive and easy-to-use simulation app that computes the current distribution and heating throughout a thermal print head design and displays the computed results in a clear, uncluttered way. The app was built with the Application Builder tool available within COMSOL Multiphysics®. ...

Better Ways to Heat and Cool Buildings

Eric Laurenz, Hannes Fugmann, Fraunhofer ISE, Germany

Adsorptive climate control systems can reduce the power required to heat and cool buildings by running primarily on waste heat, natural gas, and solar thermal energy instead of electricity. While adsorption-based chillers, heat pumps, and thermal storage units are available commercially, they need to be more efficient, compact, and cheaper to produce in order to be available on a larger scale. ...
