6 Ways Engineers Are Using Simulation to Help the Environment
Energy-efficient buildings and appliances. Safe nuclear waste storage. Well-preserved freshwater lakes. These are just a few examples of how simulation is being used to help the environment.
How Do I Use Gauge Fixing in COMSOL Multiphysics®?
Here’s your guide to using gauge fixing in your electromagnetics simulations in COMSOL Multiphysics®, from determining if it is necessary to imposing current conservation.
What Is Gauge Fixing? A Theoretical Introduction
Investigate the consequences of Helmholtz’s theorem when applied to Maxwell’s equations, and when using scalar and vector potentials to represent physical fields.
Modeling a Pacemaker Electrode in COMSOL Multiphysics®
What happens when the heart doesn’t pump the way it should? Pacemakers maintain the heart rate by monitoring natural electrical signals. Pacemaker electrodes are a key part of these devices.
Which Study Type Should I Use for My Electrothermal Analysis?
What’s the best interface to use when implementing electrothermal analyses in COMSOL Multiphysics? We go over the interfaces, study types, and multiphysics couplings for high and low frequencies.
What Is the Curl Element (and Why Is It Used)?
When solving some electromagnetics problems, the curl element (also called the edge element or vector element) can be used in the finite element method.
Modeling of NDT Methods Using COMSOL Multiphysics®
Active thermography, active ultrasonic, guided waves, acoustic emissions, and eddy current testing: 5 examples of how nondestructive testing (NDT) methods can benefit from multiphysics modeling.
How the B-H Curve Affects a Magnetic Analysis (and How to Improve It)
Magnetic soft iron steels are widely used as core materials in motors, transformers, and inductors. The B-H curve is used to describe the magnetization properties of such materials.
