- The software connects simulation with engineering systems to accelerate development.
COMSOL Multiphysics for Advanced Manufacturing
COMSOL Multiphysics software facilitates predictive modeling for next-generation electromagnetic manufacturing technologies. It achieves this by coupling electromagnetic fields with thermal, chemical, mechanical, and transport phenomena across various scales. This capability supports new approaches in electromagnetic sensing, non-destructive evaluation, and advanced materials processing.
Eddy-Current Thermometry Application
One application involves eddy-current thermometry for reconstructing three-dimensional temperature fields within metal plates. The software accounts for temperature-dependent electrical conductivity, which alters induced currents and magnetic fields, allowing for volumetric thermal inference. COMSOL simulations of defects and laser-induced transient heating are used to validate reconstruction algorithms, with multifrequency excitation explored for improved depth discrimination.
Microwave-Enabled Ceramic Additive Manufacturing
A second application focuses on microwave-enabled volumetric additive manufacturing of ceramic components. This process uses a high-power microwave beamforming array to deliver localized energy into three-dimensional volumes, enabling the processing of opaque, particle-laden resins. COMSOL models integrate electromagnetic propagation, microwave absorption, heat transfer, and ceramic sintering kinetics to predict temperature evolution, reaction progression, spatial resolution, and processing scalability.
Integration and Future Extensions
These examples illustrate how COMSOL software integrates multiphysics modeling with sensing, manufacturing, and data inversion. Future extensions for the ceramic manufacturing model will incorporate pulsed excitation, fluid flow, resin viscosity, convection, shrinkage, and solid mechanics. By connecting simulation with practical engineering systems, COMSOL-based modeling aims to accelerate technology development, reduce experimental iterations, and support reliable scale-up of electromagnetic technologies.
