How to Use State Variables in COMSOL Multiphysics®
As of COMSOL Multiphysics® version 5.5, you can use state variables to track the state of your model; affect other fields, such as material properties; and even implement hysteresis.

Material Characterization by Means of Simulation
Carbon-based materials, such as synthetic specialty graphites, are found in many industries, including solar, semiconductor, car manufacturing, ceramics, and metallurgy.

How to Perform a Sensitivity Analysis in COMSOL Multiphysics®
How do the parameters of your design affect its performance? Understanding this relationship is a valuable part of the design process. By performing a sensitivity analysis, you can do just that.

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

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

Using Web Browser Translation Tools for COMSOL Documentation
COMSOL documentation includes a lot of helpful information. Most web browsers include an automatic translation tool that enables you to read the documentation in the language of your choice.

Defeating Giant Movie Monsters Using Mathematical Modeling
The predator-prey equation can predict how we’d fare in a monster invasion, as well as real-world biology and ecology scenarios like shark overpopulation and tumor movement.
