The Ansys portfolio of simulation software facilitates the creation of multidisciplinary physics analyses — not only within the context of a single product, but also through the use of Ansys System Coupling. System Coupling can integrate multiple individual analyses, enabling you to leverage different physics solvers and/or static external data sources in a single multiphysics simulation. When two or more analyses are coupled, an examination of their combined results can capture more complex interactions than an examination of those results in isolation, producing more accurate results and yielding an optimal solution.

For example, when a fluid and structure are in contact, such as the flow over an aircraft wing or turbo-machinery blade, the fluid exerts a force on the structure, which causes the structure to displace and influence the fluid flow. This is referred to as a two-way coupling.

You can use System Coupling in several different contexts, each of which facilitates comprehensive multidisciplinary simulations between coupling participants. You can run System Coupling in:

System Coupling manages the execution of simulations between coupling participants, which are the applications or data sources that send and/or receive data in a coupled analysis. Participant support is determined by the context you're using.

For detailed examples of System Coupling use in the GUI, see the System Coupling Tutorials. For an example using PySystemCoupling, see Turek-Hron FSI2 Benchmark Example.
