Article in NASA Software Tech Briefs

Veryst Engineering published an article in the September 2013 issue of NASA Software Tech Briefs titled "Conjugate Thermal Analysis of a Generic LED Light Bulb."  The article illustrates how a coupled thermal CFD (computational fluid dynamics) analysis is used to predict the temperature vari

Article in R&D Magazine features Veryst
Dr. Jorgen Bergstrom was featured in an R&D Magazine article titled “The Indispensable Biomaterial.” Silicone elastomers have grown in importance to the medical device industry, yet their design is particularly challenging given their physical complexity. Dr. Bergstrom discusses how nonlinear finite element analysis and advanced material are facilitating the design process.
Article in the 2012 COMSOL News magazine
Veryst Engineering, in collaboration with Nordson EFD, published an article in the 2012 COMSOL News magazine titled "Modeling of Laminar Flow Static Mixers." 
Article published on The Art of Accurate Polymer Modelling
"Stress-free Simulation: The Art of Accurate Polymer Modelling" is the title of an article by Veryst's Eric Schmitt and Jorgen Bergstrom. The article appears in the October 2016 issue of Benchmark magazine, published by NAFEMS.
Blog features Veryst's work modeling fluid-structure interaction in a heart valve
Veryst’s modeling and simulation work was featured in a COMSOL blog that describes how Veryst modeled the way in which a heart valve opens and closes in response to fluid flow, providing insight that can be used to improve the design of artificial heart valves.
COMSOL blog features Veryst's work modeling, simulating bubble entrapment
Veryst’s modeling and simulation work was featured in a COMSOL blog titled “Preventing Bubble Entrapment in Microfluidic Devices Using Simulation.”  The blog describes how Veryst modeled different microchannel geometries and simulated bubble movement, providing insight that can be used to improve the design of microfluidic devices. 
COMSOL video and blog show how Veryst combines material testing and simulation for reliable results
COMSOL offers an “inside look” at how Veryst’s engineers collaborate to produce accurate and reliable simulations. 
FE software maker describes benefits of PolyUMod® models
The makers of ADINA software have announced that “in response to customers’ requirements,” ADINA supports the Bergstrom-Boyce and Three-Network viscoelastic material models, saying, “These sophisticated material models allow users to capture complex viscoelastic behaviors of polymeric components.” 
Meta Reality Labs' Research Assisted by Veryst
Meta Reality Labs (MRL), a subsidiary of Meta (formerly Facebook, Inc.), recently published an article describing their research conducted with support from Veryst's Dr. Alireza Kermani. MRL modeled ultrasound sensor integration into a glasses form factor augmented reality device, using a COMSOL model built by Veryst.
New book published on the Mechanics of Solid Polymers
Dr. Jorgen Bergstrom’s book is now available! Mechanics of Solid Polymers: Theory and Computational Modeling explains how solid polymers behave, how they can be experimentally characterized, and how to predict their behavior in different load environments.  This comprehensive book reflects the latest advances in the understanding of polymers, and shows that with the right knowledge and tools it is possible to predict accurately the response of ALL polymers.
Publication co-authored with U.S. Food and Drug Administration

Dr. Jorgen Bergstrom has co-authored (in collaboration with Maureen Dreher and Srinidhi Nagaraja of the U.S.

Publication in ASME Journal of Medical Devices
Dr. Jorgen Bergstrom et. al published an extended abstract on their work on testing and modeling the rate dependent behavior of polyether ether keytone (PEEK).
Publication in Journal of Engineering Structures Addresses Direct Shear
Dr. Alireza Kermani has co-authored an article titled "A Modal Approach to Determine Direct Shear of Beams Subjected to Impulse," and demonstrates how a modal approach provides a more accurate and less conservative estimate of direct shear.
Publication: Veryst develops advanced constitutive model for UHMWPE
Ultra-high molecular weight polyethylene (UHMWPE) is used extensively in biomedical devices due to its mechanical properties, including high impact and wear resistance. Veryst developed an advanced thermomechanical constitutive model for UHWMPE where the microstructure of the material is represented using three structural domains that capture the experimentally-observed, nonlinear, time- and temperature-dependent response at small and large strains.
