ANSYS System Coupling
ANSYS offers System Coupling as a service to manage the exchange of data and coordinate independent solver executions to accurately capture the complex interactions between physical models, typically simulated in separate solvers, that are critical in understanding the whole problem. Tight fluid-structure interactions, such as those seen in wind turbine blades and electric motor cooling applications where temperatures need to be managed, are examples of applications that rely on the power of System Coupling. The ability of System Coupling to accurately manage data exchange between the solvers needed to model the application and coordinate solver execution between them to ensure smooth convergence of the multiphysics simulation are critical for high-fidelity multiphysics simulations that impact engineering decisions.
Accurately Simulate Important Applications
System Coupling makes the simulation of a wide range of applications possible, due to the broad range of supported coupling participants. Detailed fluid-structure interaction, induction heating and thermal management modeling are examples of what is possible through connections to ANSYS Mechanical, ANSYS Fluent, ANSYS Maxwell, ANSYS CFX and ANSYS Forte. Simulations can include any number of participants. System Coupling APIs are straightforward to use when instrumenting new participants and allow the range of applications to be expanded.
Achieve Robust Results with Automatic Co-Simulation Solver Management
System Coupling synchronizes the solvers participating in a multiphysics simulation. Solver execution and tasks such as convergence checking, restarts, HPC deployment and error handling are performed. Steady/static, transient and combinations of these analysis types are possible, depending on the level of detail needed. Advanced techniques, including those used to manage cases with disparate time scales and techniques for solution stabilization and acceleration, further increase the simulation possibilities with System Coupling.
Never Compromise with Advanced and Accurate Data Exchange
Different physics solvers have different meshing best practices for achieving optimal solutions. These meshes can look quite different at the interface where multiphysics interactions occur. System Coupling employs several methods to accurately exchange data. The appropriate algorithms and mapping techniques are picked based on the quantities being exchanged with both fully conservative and profile preserving methods available. 2D-3D and 3D-3D mappings are possible. Mapping diagnostics allow mapping quality to be evaluated.
Dedicated GUI Makes Multiphysics Setup Straightforward
System Coupling is accessible inside ANSYS Workbench and from the command line. In either case, a new, intuitive graphical user interface makes connecting your solvers easy and straightforward, allowing you to specify the shared coupled regions and solver coupling settings in one place. System Coupling set up does expect the solvers involved in the multiphysics simulations to be set up first, in order to have the boundary conditions and simulation settings for the different solvers participating in the co-simulation available.
