Abaqus has a wide range of multiphysics capabilities that enable engineers and scientists to simulate the behavior of complex systems that involve the coupling of two or more physical phenomena. Here are some of the Abaqus multiphysics capabilities:

  1. Fluid-structure interaction (FSI): Abaqus has several multiphysics elements and materials that can be used to model FSI behavior accurately, such as the Coupled Eulerian- Lagrangian (CEL) method, the Arbitrary Lagrangian-Eulerian (ALE) method, and the immersed boundary method. Abaqus can model a wide range of fluid behaviors, including laminar and turbulent flows, compressible and incompressible flows, and multiphase flows.
  2. Hydrostatic-Fluid-Mechanical Simulation: The Hydrostatic-Fluid-Mechanical Multiphysics feature enables users to incorporate the impact of enclosed gas- or liquid-filled spaces in their models. This capability is valuable for simulating a wide range of applications, such as air bags, seat cushions, athletic shoes, balloons, partially filled tanks and containers, air springs, IV bags, and others. It considers the relationship between pressure and volume inside the enclosure and the energy present in the enclosed fluid.
  3. Thermal-mechanical coupling: Abaqus can simulate the interaction between thermal and mechanical behavior, such as the deformation of a structure due to thermal expansion or the temperature distribution in a structure due to mechanical loading. Abaquhas several multiphysics elements and materials that can be used to model thermal-mechanical coupling behavior accurately.
  4. Electromagnetic- thermal coupling: Abaqus can simulate the interaction between electromagnetic and thermal behavior, such as the temperature distribution in a structure due to electromagnetic heating or the magnetic field generated by a structure due to the flow of electric current. This simulation technique is valuable for delicate electronic components, including electrical traces, fuses, links, and lightbulb filaments.
  5. Piezoelectric-Mechanical Simulation: Abaqus has a comprehensive two-way electrostatic Piezoelectric-Mechanical simulation capability that enables the user to simulate the effect of the flow of electricity on the material, causing it to strain and change shape. Additionally, the simulation capability allows the user to simulate the effect of stress on the electric potential of the material.
  1. Acoustic- structural coupling: Abaqus can simulate the interaction between acoustic and structural behavior, such as the behavior of a structure subjected to acoustic waves or the generation of acoustic waves due to the deformation of a structure. Abaqus has several multiphysics elements and materials that can be used to model acoustic structural coupling behavior accurately. The interaction between structure and acoustics encompasses a broad range of applications, such as noise radiation and transmission, as well as the amplification or attenuation of acoustics.
  2. Thermal-Fluid-Mechanical Simulation: Moisture and heat can significantly impact the performance and behavior of products during assembly in various industrial processes. To determine the optimal design or manufacturing process for achieving specific performance goals, designers and engineers need to consider the product’s behavior under realistic operating conditions. Hence, it is essential to take into account the combined effects of moisture and heat on the product’s behavior.
  3. Structural-Pore Pressure Simulation: The impact of water on the behavior of soils subjected to loading is a highly intricate phenomenon, and a sophisticated coupled approach is necessary to generate reliable simulation results. These simulation results are crucial in providing assurance in making design decisions.
