Evaluating the Impact of Bearing Misalignment on Rotor Vibration
Bearings are found in devices ranging from MEMS and turbines to electric motors and even ships. How we account for a bearing’s misalignment (and the resulting rotor vibration) depends on its use.
How to Use Circular Ports in the RF Module
Degeneracy in circular ports leads to uncertainty in the mode field orientation. Not so with the Circular Port Reference Axis feature, which lets you define field orientations on port boundaries.
Speeding Up DNA Separation in a Microchannel via Simulation
DNA separation takes a long time using traditional methods. Now, researchers from the Missouri University of Science and Technology have found a faster way to get the job done.
Heat Transfer with Radiation in Participating Media and the Discrete Ordinates Method
Here’s your complete guide to the discrete ordinates method, quadrature sets, and how to model the interaction between radiation and a participating or absorbing medium.
Happy Birthday, Elsie Eaves
Elsie Eaves was one of the first female civil engineers and is celebrated as a role model for future engineers.
Is Meshing Run in Parallel in COMSOL Multiphysics®?
Meshing, an integral part of modeling in COMSOL Multiphysics®, can take up a lot of time and resources. Parallelized meshing speeds things up by distributing the meshing of domains on more cores.
Taking a Look at Electrochemical Treatment for Tumors via Modeling
EChT offers many benefits for the treatment and removal of cancerous tumors, so why isn’t it a widely accepted method yet? First, we need a better understanding of tumor destruction mechanisms.
Introduction to Numerical Integration and Gauss Points
In this comprehensive blog post, we go over the theory behind numerical integration, Gaussian quadrature, Gauss points, weak contributions, and much more.
Happy Birthday, Carl Friedrich Gauss
Gauss’ perfectionism in the field of mathematics paid off: Today, there is a statistical distribution curve and entire electromagnetics unit system named in his honor.
Using the Port Boundary Condition in Acoustic Waveguide Models
By combining several Port boundary conditions, you can easily compute the transmission and insertion loss in exhaust and muffler systems. See more benefits of this feature for acoustics modeling.
Happy Birthday, Max Planck
When Max Planck was young, a teacher told him that there was nothing left to discover in the world of physics. Fortunately for us, and the field of quantum mechanics, Planck had other plans…
How to Numerically Simplify Your Periodic RF Models
Looking for an easier way to model periodic RF structures, such as frequency selective surfaces, electromagnetic band gap structures, reactive and high impedance surfaces, and metamaterials?
