Ansys System Coupling

Accurate data exchange for multiphysics simulations

System Coupling solves multiphysics problems by connecting independent physics solvers and coordinating the exchange of the solution data, enabling accurate capture of complex interactions between physical models.

Connecting and Coordinating

Capturing Data from Physical Interactions Impacting Results

System Coupling manages data exchange and coordinates independent solver executions. Accurately capturing the complex interactions between physical models (typically simulated in separate solvers) are critical to understanding the problem. The result is smooth convergence of the multiphysics simulation for high-fidelity multiphysics simulations that impact engineering decisions.

Key Features

Ansys System Coupling streamlines the exchange of data and coordinates independent solver executions to accurately capture the complex interactions between physical models, typically simulated in separate solvers such as

The broad range of supported coupling participants makes the simulation of various applications possible. Complex fluid-structure interaction, induction heating, and thermal management modeling connect to Ansys Mechanical, Fluent, Maxwell, CFX, and Forte. System Coupling APIs are straightforward when instrumenting new participants and allow an expanded range of applications. 

Synchronizes solvers participating in a multiphysics simulation and performs convergence checking, restarts, HPC deployment, and error handling. Combinations of steady/static and transient analysis types are available, depending on the level of detail needed. Manage cases with disparate time scales and techniques for solution stabilization and acceleration, increasing the simulation possibilities with System Coupling. 

Various physics solvers have different meshing best practices to achieve optimal solutions. These meshes can look different in the interface where multiphysics interactions occur. System Coupling uses several methods to exchange data accurately. The appropriate algorithms and mapping techniques are picked based on the quantities traded with thoroughly conservative and profile-preserving methods available. Mapping diagnostics allow evaluation of mapping quality with 2D-3D and 3D-3D mappings available. 

System Coupling is accessible inside Ansys Workbench and directly from the command line. A new, intuitive graphical user interface makes connecting your solvers straightforward, allowing you to specify the shared coupled regions and solver coupling settings in one place. System Coupling setup requires the solvers involved in the multiphysics simulations first set up to have the boundary conditions and simulation settings for the different solvers participating in the co-simulation available.
