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.
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.
How Do Bicycle Pedals Stay On?
Ever wonder why the left pedal of a bike has left-handed threads and the right pedal has right-handed threads, yet the pedals stay on when riding?
Modeling a Scatterer Near an Optical Waveguide
In the real world, most structures are more complex than a 2D dielectric slab. However, if you’re designing photonic structures, you can learn a lot about wave optics modeling from this example.
