Generating Microsoft® PowerPoint® Slideshows from Your Models
Did you know that you can generate slideshow presentations of your model results in the Microsoft® PowerPoint® format as of COMSOL Multiphysics® version 5.6?
Modeling Droplet Flow in an Open Space with COMSOL Multiphysics®
If you are jogging six feet apart from someone else, should you both be wearing masks? Simulation was used to analyze the motion of particles between two runners in an open space to find answers.
Designing Inductors with a Simulation App at Bombardier Transportation
Every day, 500 million passengers in 200 cities and 60 countries ride a train featuring Bombardier Transportation products. See how apps help speed up the design process for a train component…
Model Vortex Lattice Formation in a Bose–Einstein Condensate
Bose–Einstein condensation can cause superfluidity, superconductivity, lasers, and trapped dilute cold atoms. When such systems are subjected to rotating perturbation, it forms a vortex lattice.
Accelerating Model Convergence with Symbolic Differentiation
Whenever you set up and solve a nonlinear problem in COMSOL Multiphysics, a symbolic differentiation engine is automatically used to ensure high robustness and accelerate model convergence.
It’s a Bird, It’s a Plane, It’s…Gravity-Defying Spiders!
Spider ballooning, in which spiders float for miles, was originally observed by Charles Darwin in 1832. Since then, researchers from University of Bristol used simulation to study this effect.
How to Create High-Quality Model Images in COMSOL Multiphysics®
Whether you’re including model images in a presentation, article, paper, or on the web, you want them to be high quality. These guidelines for image creation can help.
Equation-Based Modeling with a Space-Time Discretization
In COMSOL Multiphysics®, almost any expression in a computational model can be modified. For example, using a space-time discretization can make optimization problems easy and fast to implement.
Exploring the Ambiguity of Hardness Numbers with COMSOL®
To help customers easily obtain stress-strain curves from indentation test data, this guest blogger turned to simulation applications and COMSOL Compiler™ — and created a brand new product.
The Growing Use of Simulation in Pharmaceutical Development
Did you know that the development cycle of a drug can take years and cost millions of dollars? Simulation is 1 way to make pharmaceutical development processes faster and more cost effective.
Implementing a Damage Evolution Law for a Hyperelastic Material
By implementing a physically motivated damage evolution law for a hyperelastic material, you can incorporate material softening, creep, and stabilization of hysteresis curves during cycling.
Estimating Hyperelastic Material Parameters via a Lap Joint Shear Test
For rubber, polymers, and biological tissue, the relationship between stress and strain is nonlinear, even at small loads. The lap joint shear test can be used to determine material properties.
