Studying Shock Wave Phenomena with a Shock Tube Application
Shock waves used to be a theoretical problem only. Then, shock tubes enabled experimentation, but it was costly and inefficient. Enter numerical modeling applications.
FEM vs. FVM
Finite element methods, finite volume methods, or a hybrid approach: Which is the best choice for CFD? It depends on the fluid flow problem you’re trying to solve.
Using Discontinuous Meshes for Conjugate Heat Transfer Modeling
You can use different discontinuous meshes in neighboring domains in COMSOL Multiphysics®. This capability comes in handy, particularly when modeling conjugate heat transfer problems.
How to Export (and Share) Your 3D Result Plots as glTF™ Files
Wow your project stakeholders by sharing your 3D COMSOL Multiphysics® results as glTF™ files. We show you how to export plots and share them in third-party graphics viewers.
How to Activate Material in Simulations of Manufacturing Processes
Do you model manufacturing processes such as welding or additive manufacturing? You can activate or deactivate a material in a material deposition simulation using specialized functionality.
Course: Defining Multiphysics Models
There are 3 approaches to setting up a multiphysics model in the COMSOL® software: Fully automatic, manual with predefined couplings, and manual with user-defined couplings. Here, we discuss #1.
3 Approaches to Modeling Moving Loads and Constraints in COMSOL®
Learn 3 ways to model moving loads and constraints in COMSOL Multiphysics®: using variables, interpolation functions, and paths imported from CAD geometries.
Nonstandard Constraints and the Power of Weak Contributions
For a flexible and physics-independent way to extend the applicability of the COMSOL Multiphysics® software, you can implement nonstandard constraints using the so-called weak contributions.
