In this COMSOL tutorial for beginners, you will learn how to couple COMSOL Electrostatic Module with an Electrical Circuit to create powerful finite element simulations. We walk through adding electrical circuit physics to a project, defining circuits in COMSOL Multiphysics, and integrating electrical circuit elements seamlessly into your model. In this tutorial, a capacitor in the FEM domain is connected to a voltage source and a resistor to model an RC circuit and a low-pass filter. • Discover how to set up external device coupling in electrical circuits, define time-dependent study settings for an RC circuit, and plot node voltages and device currents versus time. You'll also learn how to create dual Y-axis plots for comparison, activate the frequency domain study, and plot the filter magnitude response in dB against frequency. • We guide you through calculating the 3dB cut-off frequency of and RC low-pass filter from both magnitude and phase responses, allowing for complete circuit analysis. If you're interested in filter design, frequency domain analysis, or integrating the electrostatic module with external circuits in COMSOL, this video covers everything you need! • Don't miss out on mastering COMSOL’s circuit simulation tools, perfect for professionals and students in electrical engineering.
