In the final installment of our Chemical Kinetics blog series, we discuss the complex and nonlinear process of synthesizing ammonia. Get an overview of the equations and modeling considerations.
Natural Frequencies of Immersed Beams
A guest blogger from Veryst Engineering demonstrates the modeling of a cantilever beam immersed in a fluid to study its natural frequencies. Read it here >>
Tips for Using the Wall Distance Interface
The Wall Distance interface can be used to calculate the distance to the nearest wall or detect when a moving object will hit a wall. Learn how to implement this interface in CFD simulations.
What Kinds of FSI Problems Can COMSOL Multiphysics Solve?
We discuss the various techniques for modeling fluid–structure interaction (FSI) in the COMSOL® software, as well as highlight the add-on modules you need for these various types of analyses.
Characterizing the Flow and Choosing the Right Interface
No matter the focus of your modeling project, you have probably had to consider fluid flow at some point. Here, we discuss how to characterize the flow and choose the correct CFD interface.
