Abaqus 6.10: Multiphysics and Assembly View Cuts

What happens when saline fluid and human tissues travel through the same tube in a medical device? This is one example of a scenario best served by multiphysics simulation, where the behaviors of liquid and solids must both be given equal consideration. In Abaqus 6.10, the latest release of Dassault Systemes’ (DS) Finite Element Analysis (FEA) package, you can simulate this type of multiphysics event.

Multiphysics simulation has been available in Abaqus since 1979, beginning with Abaqus V2, according to DS’ site for SIMULIA. So what exactly is new with this release? Abaqus product managers explained that this marks “the first native computational fluid dynamic (CFD)” multiphysics in the software.

Abaqus, part of Dassault’s SIMULIA product line, comes in four variations:

• Abaqus/CAE
• Abaqus/Standard
• Abaqus/Explicit
• Abaqus/CFD

With multiphysics now available in Abaqus/CFD, you can perform coupled physics simulations with Abaqus/Standard (best suited for static and low-speed dynamic events) and Abaqus/Explicit (brief transient dynamic events) to understand liquid-solid interactions. With abaqus/Standard, you might simulate sealing pressure in a gasket joints, steady-state tire rolls, and cracks in airplane fuselages. With Abaqus/Explicit, you might examine cellphone drops, automotive crashes, and ballistic impacts.

DS supports direct code coupling with partner products (such as CD-Adapco, ACU-SIM, and Capvidia) and customer-developed codes. It also allows code coupling via MpCCI, an interface developed by Fraunhofer Institutes for Algorithms and Scientific Computing.

Previously, Abaqus has a tool that lets you examine your parts in cross-sectional views using its View Cut function. This function is now available in assembly mode with Release 6.10.
