Get a quick introduction to paper mechanics before guest blogger Eric Linvill discusses modeling a L&W bending resistance test piece for cost-benefit analyses in paperboard production.

Finite element modeling can be used to analyze the mechanical behavior of biological cells. Guest blogger Björn Fallqvist of Lightness by Design sheds light on this bioengineering topic.

Cars with subpar mufflers are annoyingly loud. Guest blogger Linus Fagerberg from Lightness by Design discusses a novel, simulation-based approach to predict noise generation in muffler designs.

Today, guest blogger and Certified Consultant Ionut Prodan of Boffin Solutions, LLC discusses using a hybrid approach to calculate fracture flux in thin structures. When modeling thin fractures within a 3D porous matrix, you can efficiently describe their pressure field by modeling them as 2D objects via the Fracture Flow interface. Significant fracture flux calculation issues, however, may arise for systems of practical interest, such as hydraulic fractures contained within unconventional reservoirs. See how a hybrid approach overcomes such difficulties.

Today, we welcome Managing Director Dr. Alfred J. Svobodnik of Konzept-X GmbH, a COMSOL Certified Consultant and developer of multidisciplinary virtually optimized industrial design technology (M-voiD® technology). MP3 players, smartphones, and tablets allow us to listen to our favorite music almost everywhere. While driving in a car, we should also enjoy the highest sound quality. Learn how to use simulation to reproduce sound in one of the most difficult environments — a vehicle — to design better automotive sound systems.

A guest blogger from Noumenon Multiphysics writes about modeling phase change in a thermosiphon, a device that has been keeping houses warm since the 1800s.

Guest blogger Linus Fagerberg from Lightness by Design follows up a previous post with a discussion of one design consideration for the radiated sound in a muffler design: shell thickness.

Guest blogger Thomas Clavet of EMC3 Consulting discusses the simulation of ultrasound focusing via phased array and geometrically focused probe designs for clinical uses.

Today, guest blogger Matteo Lualdi of resolvent ApS, a COMSOL Certified Consultant, discusses the benefits of creating a simulation app to analyze a solid oxide fuel cell stack. For many businesses, numerical modeling and simulation are valuable tools at various stages of the design workflow, from product development to optimization. Apps further extend the reach of these tools, hiding complex multiphysics models beneath easy-to-use interfaces. Here’s a look at one such example: a solid oxide fuel cell stack app.

Today, guest blogger Linus Fagerberg of Lightness by Design, a COMSOL Certified Consultant, shares how multiphysics simulation provides accuracy in automotive muffler design. The acoustic design of mufflers in the automotive industry has traditionally been performed by an iterative process where different alternatives are compared by experimental methods until a satisfactory design is found. Numerical simulation can drastically reduce a project’s time and expenses, while simultaneously increasing the performance of the muffler.
