ABAQUS/MULTIPHYSICS

Multiphysics Technology is an integral part of ABAQUS Unified FEA product suite. With the unified approach of using same model, material, element library and other finite element conditions, ABAQUS models can be quickly extended to include additional physical interactions without any additional tools and interfaces.

The multiphysics technologies that can be used to model fluid flow in FSI problems and extreme deformation are:

  • Coupled Eulerian-Lagrangian (CEL)

The approach enables engineers to simulate structural tests with fluid loads more realistically. Applications are Tank sloshing, Tire hydroplaning, Soil structure interaction etc.

  • Smoothed Particle Hydrodynamics (SPH)

This approach is useful in simulating bulk matter in motion such as extremely violent fluid flow or shattering of metals. Applications include Airbag deployment, Ballistic impact etc.

  • Discrete Element Method (DEM)

An extremely useful approach for modeling granular particles. It can be used in a variety of applications such as shot peening on metals, granular sand in wheel-soil interaction, tablets in mining industry, conveyors etc.

Abaqus_CFD_064

ABAQUS/CFD

ABAQUS/CFD is the Computational Fluid Dynamics solver for fluid flow analysis aimed at structural engineers.

It is capable of simulating incompressible transient or steady flows, turbulent or laminar as well as conjugate heat transfer and Fluid-Structure Interaction (FSI).

To gain a competitive advantage in the marketplace, manufacturers have started to leverage the robust capabilities of realistic simulation to lessen dependency on physical testing, reduce part weight, or evaluate the use of alternative materials during the product design phase to ensure optimum product performance.

ABAQUS provides Realistic Simulations for all industries and has both implicit and explicit solvers integrated in one Graphical Users Interface allowing to share models between both solvers.  Using ABAQUS allows companies to reduce their FEA toolset.

With its leading technology in contact modeling and non-linear materials, ABAQUS offers more accurate simulations and better correlation between tests and analysis results.
