Specifying Boundary Conditions and Constraints in Variational Problems
In part 2 of a blog series on solving variational problems in COMSOL Multiphysics®, we discuss how to specify general boundary conditions and constraints.
How to Model the Compression of a Hyperelastic Foam
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
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
Hermann von Helmholtz made major contributions to the fields of physiology, optics, electromagnetism, and more. He also notably challenged common perceptions in science using philosophy.
Seeing Through Solids: Discovery and Applications of Photoacoustics
The field of photoacoustics started with Alexander Graham Bell and some sunlight. Now, photoacoustic imaging is used for nearly anything involving generating images of opaque material samples.
How to Model Ion-Exchange Membranes and Donnan Potentials
Get an introduction to the theory behind the Nernst-Planck-Poisson equations, Donnan potentials, and how to model ion-exchange membranes in batteries and fuel cells.
How to Model Sparging in COMSOL Multiphysics®
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
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.
