Navigate the COMSOL graphical user interface to model fuse elements, inductors, and a parallel plate capacitor, extracting resistance, inductance, capacitance, and temperature rise.
Meet Rahul, IIT Bombay PhD, who uses Comsol Multiphysics to analyze electromagnetic effects in vacuum circuit breakers and vacuum arcs, with experience in switchgear, permanent magnet motors, and high-frequency transformers.
Explore the COMSOL graphical user interface and workflow, comparing model wizard and blank model setups for 3D and axisymmetric electric currents, with standard steps to results visualization.
Explore the application library to open the Echo Transformer model and review physics interfaces and solved results, then export geometry to mph bin and use insert sequence to replay steps.
Start from model in COMSOL Multiphysics, set millimeter units, build a 3D component with a workplane, sketch a rectangle, array circles, subtract, and extrude to create the fuse element geometry.
Learn to build a three-dimensional COMSOL Multiphysics model, assign copper, set electric currents in a stationary study, and extract the resistance of the fuse via surface terminal conditions.
Couple heat transfer in solids with electromagnetic analysis to determine device temperature, using ohmic heating, convective boundary conditions, and both steady-state and time-dependent temperature evolution.
Use a parametric sweep in comsol multiphysics to determine the fuse current rating by tracking the fuse temperature as current varies, comparing with copper melting point to yield 88 A.
Model a coil in comsol with a 3d magnetic fields interface and stationary study, then extract its resistance and inductance.
Model a 3D capacitor in COMSOL Multiphysics using the electrostatics interface and a stationary study to compute capacitance, with quartz dielectric and an air domain.
This course is a quick introduction to COMSOL Multiphysics® for people who are completely new to the software. It is an entry point for further exploration of COMSOL for electromagnetic simulations.
It is structured in the form of simple tutorials demonstrating how to model a resistive device, an inductance and a capacitance. In each tutorial, new geometry operations, physics interface features, model specific insights and tips are discussed, to make learning more effective, in context.
Course structure:
Section 1: Introduction
Introduction to the course and instructor.
Section 2: Getting started
Learning the COMSOL GUI, workflow, and basic geometry operations.
Section 3: Modeling an electric fuse
Electromagnetic simulation to obtain resistance, thermal coupling to obtain the temperature, and use of parametric sweep to determine the current rating of the fuse.
Section 4: Modeling an inductor
Electromagnetic simulation of an air core coil to obtain resistance and inductance.
Section 5: Modeling a capacitor

Why take this course:
Learning from my struggles as a student using COMSOL for the very first time, and then insights gained after acquiring comprehensive knowledge from my role as an Application Engineer in COMSOL India, I have designed the course to address the pain points of an absolute beginner. In this course, each consecutive tutorial builds step-by-step upon the learnings of the previous one, to systematically develop your skillset toward independent exploration.
