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 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.
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.
Reducing the Magnetic Signature of a Submarine
For a submarine to avoid detection and remain “under the radar”, engineers need to investigate the magnetic signature of the vessel’s design. Electromagnetics simulation is up to the task.
How to Use Numeric Ports in Your RF Analyses
When performing RF analyses in the COMSOL® software, you can use numeric ports to compute the mode of a port with an arbitrary shape. This demonstration includes a waveguide adapter example.
Plotting Spatial Derivatives of the Magnetic Field
Radiology, magnetophoresis, particle accelerators, and geophysics are all areas where it is useful to compute the spatial derivative of the magnetic field or magnetic flux density.
