Introduction to the System Coupling User's Guide

The System Coupling User's Guide describes how to use the current version of Ansys System Coupling to direct two or more otherwise independent physics solvers and/or external data sources to work together in a coupled multiphysics analysis — for example, in a Fluid-Structure Interaction (FSI) analysis.

System Coupling User's Guide Contents

This guide covers the following topics:

  • System Coupling Overview offers a high-level overview of the core coupling functionality available for all analyses run using System Coupling, including troubleshooting information, migration instructions, and a listing of current known issues and limitations.

  • Using System Coupling's User Interfaces describes how to set up and execute coupled analyses using System Coupling's graphical user interface (GUI) and command-line interface (CLI).

  • Using System Coupling in Workbench describes how to set up and execute coupled analyses using System Coupling in Workbench.

  • Coupled Analysis Management describes the processes System Coupling uses to manage coupled analyses and co-simulations.

  • System Coupling Data Transfers provides detailed and context-agnostic information about data transfers, including the rules that govern their creation, the overall data-transfer process, and details about the mapping and supplemental processing algorithms used by System Coupling.

  • System Coupling Input and Output Files describes the files that System Coupling consumes and produces during the setup and execution of a coupled analysis.

  • Common Engineering Applications for System Coupling provides information on some of the different types of analyses supported by System Coupling.

  • Best Practices for System Coupling provides both generally applicable and application-specific best practices and recommendations for setting up and running coupled analyses.

Additional Resources

In addition to this guide, the following System Coupling documentation is available:

  • System Coupling Settings and Commands Reference provides a comprehensive listing of System Coupling's data model settings, commands, built-in variables, and command-line options.

  • System Coupling Beta Features gives instructions for accessing and using the hidden features offered by System Coupling in the 2024 R2 release.

  • System Coupling Tutorials includes tutorials that provide guidance on using System Coupling, demonstrating its use in specific co-simulation applications.

  • System Coupling Participant Library documentation for System Coupling's C, C++, Fortran, and Python APIs is available on the Ansys Developer Portal site. It includes reference materials, examples, tutorials, and instructions on how to use APIs to connect independent solvers to a System Coupling co-simulation.
