Using Transfer-Matrix Computation to Analyze Wax Guard Acoustics

January 28, 2020

The wax guard is an important part of a hearing aid, as it can improve the functionality and overall lifespan. We feature an acoustics model of a wax guard based on an actual industry example.

How to Use Topology Optimization Results as Model Geometries

January 24, 2020

Oftentimes, topology optimization is not the last step in your design process. In fact, you can use the results from a topology optimization study as model geometries for your next analysis.

How to Use an Add-In to Convert Images to Geometry Models

January 23, 2020

Did you know that you can draw an image, import it into COMSOL Multiphysics®, and the Image to Curve add-in will create an interpolation curve from a contour plot of the image?

Developing a Silicon MEMS Chip for On-Demand DNA Synthesis

January 21, 2020

The development of genome editing tools like CRISPR-Cas9 has increased the demand for DNA synthesis technology. Researchers are creating a DNA synthesis platform to broaden horizons in the field.

Which Study Type Should I Use for My Electrothermal Analysis?

January 13, 2020

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.

How to Simulate Control Systems Using the PID Controller Add-In

January 9, 2020

A PID controller can be used in a variety of industries. This blog post demonstrates how a PID controller add-in can be easily incorporated in two simulation examples.

How to Customize Your Model Builder Workflow Using Add-Ins

January 3, 2020

By creating and using add-ins, as well as building your own add-in libraries or using the built-in library in COMSOL Multiphysics®, you can customize and streamline your Model Builder workflow.

What Is the Curl Element (and Why Is It Used)?

December 30, 2019

When solving some electromagnetics problems, the curl element (also called the edge element or vector element) can be used in the finite element method.
