Digital Twins and Model-Based Battery Design
By combining high-fidelity multiphysics models with lightweight models and measured data, engineers can create digital twins to understand, predict, optimize, and control real-world systems.

Digital Twins: Not Just Hype
The term “digital twin” has been called everything from just hype to a revolutionary concept. We use a jet engine example to explain the concept of digital twins and how simulation fits in.

Simulating Fluid-Structure Interaction in a Ball Check Valve
Simulate FSI in a ball check valve to find the flow rate, fluid pressure, and fluid velocity. The COMSOL® software includes a predefined multiphysics coupling that makes it simple.

2 Mesh Adaptation Methods: Enabling More Efficient Computations
Why adapt your mesh? For one thing, it helps you solve your computational problems more efficiently. Here, we show you 2 methods for adapting your mesh in COMSOL Multiphysics®.

Keynote Video: Enhancing STEM Education with Simulation
Ivana Milanovic uses simulation to teach undergraduate students in her science, technology, engineering, and math (STEM) courses, as she explains in her COMSOL Conference 2018 presentation.

A Guide to Publishing and Licensing Simulation Applications
Interested in protecting the proprietary rights of the simulation applications you create and distribute? We walk you through 2 ways to set up licensing terms and conditions.

Performing Topology Optimization with the Density Method
The density method simplifies the process of topology optimization. Get an overview of how to use a special density feature for topology optimization in the COMSOL® software.

How to Create Custom Reports Using Report Templates
You can document and showcase your simulation setups and results with reports. To make this process more efficient, COMSOL Multiphysics® includes tools for creating easy-to-use report templates.

Keynote Video: Improving Synchrotron Light Sources with Applications
For synchrotron light sources, brighter is better: RadiaSoft LLC creates and deploys wave optics simulation applications to design improved vacuum chambers for a synchrotron upgrade project.

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.
