The physical disciplines of structural mechanics, fluid dynamics, thermodynamics, and electromagnetics are closely linked, with multiphysics interactions crucial in many industrial applications. For example, designing lithium-ion batteries involves accounting for electrochemical behavior, thermal runaway, fluid dynamics, and structural effects. Similarly, manufacturing processes require control over multiphysical effects like plastic flow and moisture build-up. The Abaqus Unified FEA suite, with its extensive multiphysics capabilities developed over decades, has been widely used in various engineering applications. Since Abaqus V2 in 1979, multiphysics features like fluid, thermal, and electrical couplings have continuously expanded its versatility.
Abaqus provides versatile multiphysics simulation capabilities, including:
- Sequential Results Mapping: This feature allows users to map results from external simulations into Abaqus, such as transferring temperature from a heat transfer simulation or pressure from a fluid dynamics simulation.
- Fully-Coupled Simulation: For more complex interactions, Abaqus offers fully coupled procedures, including thermal stress, thermal-electrochemical-structural, acoustic-structural, and fluid flow through porous media.
- Co-Simulation: An open framework enables integration with external solvers for co-simulation.
Thermal-Mechanical Simulation
Thermal-mechanical interaction can vary from simple thermal stress analysis, where thermal simulations inform stress assessments, to more complex scenarios like friction-induced heat generation, as seen in brake systems. It can also encompass fully coupled simulations that account for how motion influences heat transfer and vice versa.
Structural-Acoustic Simulation
Structural-acoustic interaction spans a wide range of applications, including noise transmission, radiation, and acoustic attenuation or amplification. Abaqus seamlessly integrates noise simulation within its finite element solver, enabling fully coupled structural-acoustic analyses to be conducted using familiar workflows.
Coupled Eulerian-Lagrangian Simulation
The Coupled Eulerian-Lagrangian (CEL) method in Abaqus allows engineers and scientists to address problems where fluid-structure interactions are crucial. This approach eliminates the need for multiple software products by solving fluid-structure interaction (FSI) problems simultaneously within the Abaqus environment.
