Coupling Piezoelectric, Thermal, and Structural Analyses in COMSOL®
Duration: 58:18
Watch this archived webinar, originally hosted by IEEE Spectrum, to learn how to couple piezoelectricity, structural vibration, and heat transfer with the COMSOL Multiphysics® software.
Kyle Koppenhoefer of AltaSim Technologies demonstrates how to perform a fully coupled piezoelectric, structural vibration, and thermal analysis of a structure. He also discusses the simulation results used for predicting temperature distribution in the structure and how heating affects its resonance frequency.
