Multiparameter Optimization with a Least-Squares Objective
Learn how to estimate parameters using multiparameter optimization, which will automatically adjust your model based on an underlying data file of experimental parameters.

Optimizing the Geometry of Optical Antennas with Genetic Algorithms
What does antenna design have to do with the concept of natural selection? Although it may sound far-fetched, the basic principles of natural selection can be used to optimize antenna geometries.

Finding the Ideal Thickness for the Insulation of a Pipeline
Pipelines need to be properly insulated in order to transport products like petroleum and natural gas across long distances. Use COMSOL® to find the ideal thickness for a pipeline insulation.

The Optimal Workflow for Complex Modeling Projects on a Deadline
You’re working on a complex modeling project under a tight deadline, and your computation is taking a long time to solve. You can breathe easier by using this optimized workflow for such scenarios.

How to Create Electrostatics Models with Wires, Surfaces, and Solids
Here’s a guide to building models that combine wires, surfaces, and solids using the electrostatics features based on the boundary element method that are available with the AC/DC Module.

Streamlining the Design of Frequency-Selective Surfaces
If you want to improve the frequency response of a frequency-selective surface, you have many options for methods. 1 method streamlines what can be a complex process: simulation applications.

How to Create Graphs with Two Y-Axes in COMSOL Multiphysics®
Did you know that you can add a second y-axis to a 1D plot to include two scales of values in your simulation results? This blog post details how and also includes a video demonstration.

Introduction to Designing Microwave Circuits Using EM Simulation
When it comes to designing RF, microwave, and millimeter-wave circuits with electromagnetics simulation, the key is to start simple and gradually add complexity to your analyses.
