Forming New Ideas with Generative Design in COMSOL®
Pencils were invented in the 16th century and erasers in the 18th century. However, it wasn’t until the 19th century that erasers were attached to pencils in the typical design we know today.
Why Do Golf Balls Have Dimples?
Why do golf balls have dimples? Can I model a golf ball with COMSOL Multiphysics? Can I use simulation to optimize my shot and make a par? Find answers to these questions and more…
Micromagnetic Simulation with COMSOL Multiphysics®
A guest blogger from Fudan University in China used the Physics Builder in COMSOL Multiphysics to create a “Micromagnetics Module” for performing micromagnetic simulations.
How to Model Metabolic Reaction Networks with COMSOL®
Certain ice creams, puddings, and candies have an extremely vivid yellow color that comes from vitamin B2. The manufacturing of this supplement is one example of a metabolic reaction network…
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.
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.
