Dear Desktop Engineering Reader:
John Donne famously wrote that no man is an island entire of itself. If his eyes had seen existence from multiphysical rather than a metaphysical point of view, he might have said that no island is entire of itself. An island, after all, is merely a collection of physical elements that are constantly assailed by the forces of physics that are nature. Thus, Donne might have reasoned, no physical creation — natural or man-made — is entire of itself from the force of physics.
And this, dear reader, is among the reasons why I believe multiphysics analysis is were it’s at. No part is entire of itself. It, with all its inherent weaknesses against nature stemming from its core properties, must exist in an world of multiple physics. How you engineer that part to endure the conditions it will be assailed by is key to the engineering success of your creation. And this is also why I was greatly intrigued by the new multiphysics technology in Abaqus Release 6.10 from the SIMULIA unit of Dassault Systèmes. It can help you optimize your parts and assemblies to withstand the buffeting physics has in store for them.
Abaqus, as you no doubt know, is top-shelf analysis power, but it’s power that’s easy enough to use for either routine or exotic engineering problems. Abaqus is really a suite of applications covering a spectrum of analyses from FEA to static and low-/high-speed dynamic events to advanced CFD jobs. If you know the Abaqus product suite well, what you have here is the capability of running CFD simulations that couple Abaqus/Standard and Abaqus/Explicit. If not, the multiphysics coupling means that you can analyze, visualize, and predict your creation’s behavior during real-world events such as fluid-structure interaction between human tissues, convection cooling in electronic systems, and the like.
Abaqus 6.10 also delivers on more than 100 enhancements, many user-driven, ranging from modeling, performance, and usability to visualization and core mechanics. Its well-regarded fracture analysis capabilities, which you really want if you’re designing nuclear power plant components or something, have been enhanced to better improve the the process for modeling fracture of composite materials.
You can read all about the new features and enhancements in Abaqus 6.10 in today’s Pick of the Week write-up and at the far end of the links the DE Editors have provided for you. BTW, make sure to hit those links and check out the animations along the side of the Abaqus/Standard and Abaqus/Explicit web pages. They’re elegant.
It’s always take-notice news when a leader comes out with an upgrade. Such is the case with today’s Pick of the Week from SIMULIA. Recommended.
Thanks, Pal. — Lockwood
