A data transfer is the transfer of a single quantity type in one direction between source and target regions of two participant meshes. For System Coupling in Workbench, each data transfer is defined by a variety of user interface settings such as Source, Target, and Data Transfer Control.
For more information on supported data transfers, see Participant Variables and Quantity Types Supported by System Coupling.
For information on the data transfers that are supported for a given participant system, use the links in Supported Coupling Participants for System Coupling in Workbench to review participant product documentation.
When you create data transfers using the Create Data Transfer context option in the System Coupling tab's Outline of Schematic, the following rules apply:
For a given target region, there can only be one source region.
Thermal data can be transferred:
between Fluent and Mechanical directly through System Coupling,
between CFX and Mechanical directly through System Coupling, and
through the coupling of an External Data component system.
For one-way thermal transfers, only one of the above three options above can be defined for a given pair of source and target regions.
For data transfer creation details that are generally applicable to all System Coupling contexts, see Rules for the Creation of Data Transfers.
