The co-simulation technique is a multiphysics capability that provides run-time coupling of Abaqus analysis programs. You can divide a model into multiple domains and use different analysis programs to obtain solutions for each domain. For Abaqus/Standard to Abaqus/Explicit co-simulation, each Abaqus analysis operates on a complementary section of the model domain where it is expected to provide the more computationally efficient solution. For example, Abaqus/Standard provides a more efficient solution for light and stiff components, while Abaqus/Explicit is more efficient for solving complex contact interactions.
You define the interface region across which fields are exchanged and the coupling schemes. For more information, see “Structural-to-structural co-simulation,” Section 17.3.1 of the Abaqus Analysis User's Guide, and “Fluid-to-structural and conjugate heat transfer co-simulation,” Section 17.3.2 of the Abaqus Analysis User's Guide.
