Digital Twins: Not Just Hype
The term “digital twin” has been called everything from just hype to a revolutionary concept. We use a jet engine example to explain the concept of digital twins and how simulation fits in.
Keynote Video: EPFL Uses Simulation to Design a Hyperloop Pod
The EPFLoop team used multiphysics simulation to design the aeroshell, pressure vessel, and braking system of their hyperloop pod for the SpaceX 2018 competition. Get an inside look here.
Studying Presbyopia with an Optomechanical Model of the Human Eye
You have to see this multiphysics simulation research: To help combat the effects of presbyopia in aging eyes, Kejako built a 3D optomechanical model of a full human eye.
Image Denoising and Other Multidimensional Variational Problems
Learn how to solve variational problems featuring multiple dimensions, higher-order derivatives, and multiple unknowns with a fun example: image denoising in a grainy photograph.
Methods for Dealing with Numerical Issues in Constraint Enforcement
This post is helpful if you use equation-based modeling: Learn a variety of different methods for dealing with numerical issues when enforcing constraints in variational problems.
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.
Describing Viscoelastic Behavior with an Oldroyd-B Benchmark
The Oldroyd-B model is used to define viscoelastic behavior in fluids such as clay, toothpaste, and oil. We present a benchmark model for a fluid with viscoelastic behavior under strain.
