Happy Birthday, Marie Van Brittan Brown
Today, home security is a billion dollar industry that relies on smart devices. However, it all started with a nurse who wanted to feel safer in her home in Queens, New York.
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.
