Add a Full State-Space Feedback Controller to a Control System Model
Get a brief overview of full state feedback, learn how to use the State-Space Controller add-in, and get a demonstration of implementing the add-in using a mass-spring-damper system example.

Combining Adaptive Mesh Refinement with Data Filtering
In a follow-up to our previous blog post on data filtering, we demonstrate how to implement adaptive mesh refinement and a Helmholtz filter for a thermal model with a nonuniform heat load.

Using Data Filtering to Improve Model Performance
Want to include experimental data in your model as a load or boundary condition, but the data varies over space or time and is noisy? Try implementing data filtering, such as a Helmholtz filter.

How to Model a Hall Effect Sensor with COMSOL Multiphysics®
Basic working principle of a Hall effect sensor: A nearby magnetic field deflects the path of current through a semiconductive sensor, which causes a measurable change in potential.
