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.
Editing and Repairing Imported Meshes in COMSOL Multiphysics®
COMSOL Multiphysics® includes several operations for modifying imported surface meshes. You can create, intersect, partition, and join entities, adapt and refine mesh elements, and more.
Designing District Heating Networks Using Topology Optimization
District heating networks help power plants reach high efficiencies by utilizing cogeneration, which is especially helpful in the winter. How does topology optimization fit in? Keep reading…
How to Convert Point Cloud Data to Surfaces and Solids
Sometimes, the only data you have before starting an analysis project is a set of points (also known as a point cloud). Did you know that a point cloud can be converted into a model geometry?
Using Global Equations to Introduce Fully Coupled Goal Seeking
Learn how to introduce a goal-seeking equation, combined with a fully coupled approach, to solve a nonlinear model. (Follow-up to an earlier blog post on goal seeking with a segregated solver.)
Introducing Goal Seeking into the Segregated Solver
Did you know that you can adjust a model input to achieve a desired output in your nonlinear problems? The process involves implementing a global equation into the segregated solver.
