How to Model the Compression of a Hyperelastic Foam

September 5, 2018

When characterizing hyperelastic materials, how do you ensure accuracy? Here, we show how to model the compression of a sphere made of an elastic foam using experimental data.

Introduction to Modeling Soap Films and Other Variational Problems

September 4, 2018

In this introduction to a 5-part series, learn how to solve variational problems using equation-based modeling, which is useful for modeling soap films, catenary cables, light beams, and more.

Happy Birthday, Hermann von Helmholtz

How to Model Sparging in COMSOL Multiphysics®

August 22, 2018

Sparging, the process of bubbling a gas into a liquid, is seen most notably in carbonation, such as for soda and seltzer water. This mass transfer process can be modeled in COMSOL Multiphysics®.

Examining Vibration in a Lumped Model of the Human Body

August 21, 2018

Engineers working to reduce the effects of whole body vibration (WBV) in transportation methods can analyze their systems and designs using a lumped model of the human body.

How to Place Inlet and Outlet Boundary Conditions in CFD Simulations

August 20, 2018

When setting up fluid flow simulations, at what distance can we apply boundary conditions without interfering with the process? Here, we discuss how to place inlet and outlet boundary conditions.
