Accelerating Model Convergence with Symbolic Differentiation

October 29, 2020

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!

October 27, 2020

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®

September 30, 2020

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

September 24, 2020

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®

September 22, 2020

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

September 17, 2020

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

September 8, 2020

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

September 3, 2020

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.
