Introducing the Ray Optics Module
COMSOL Multiphysics version 5.0 introduced an add-on module for electromagnetics modeling: the Ray Optics Module. It can be used to perform ray tracing and geometrical optics studies.
Understanding Parallel Computing
Q: Do you use parallel computing to run your COMSOL Multiphysics® simulations? If so, you may enjoy this conceptual overview of computers and the algorithms used by the COMSOL® software.
Modeling a Coil Heat Exchanger
Coil heat exchangers are simple and easy to manufacture — but what about modeling them? Adding expressions to compute the temperature drop between coil turns simplifies the modeling process.
Exploiting Symmetry to Simplify Magnetic Field Modeling
Get an introduction to the types of symmetry boundary conditions that you can exploit in your EM models.
Getting the Most out of Client-Server Mode
Learn how to use Client-Server mode when modeling in COMSOL Multiphysics® on a Floating Network License — and see why it is beneficial for you to do so.
How to Integrate Functions Without Knowing the Limits of the Integral
Did you know that the COMSOL® software can solve integrals as well as partial differential equations? Learn how to integrate functions — even without knowing the limits of the integral.
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.
Modeling the Hydrostatic Pressure of a Fluid in a Deformable Container
Picture a water balloon being compressed at the center. As you squeeze the balloon, the locations of the highest point and depth of fluid change, altering the hydrostatic pressure distribution.
