Participant Variables and Quantity Types Supported by System Coupling

System Coupling supports the use of any vector or scalar variables. For participant-specific information on the variables can be transferred via System Coupling, see the corresponding participant documentation:

To facilitate most common coupling workflows, System Coupling also provides data transfer quantity types that are referenced by participant variables. Coupling participants declare variables of a given quantity type, and System Coupling ensures that data transfers are created between variables of the same/compatible quantity type.

Available quantity types are listed in the table below.

Table 4: Data transfer quantity types supported by System Coupling

Quantity Type1

Force

Incremental Displacement 5

Heat Rate 6

Temperature

Heat Transfer Coefficient 7

Convection Reference Temperature 6

Mode Shape

Electric Conductivity

1: Quantity types noted in this table are in SI units.

2: All vector quantities consist of three Cartesian components.

3: The type of mapping used depends on whether the variable is or extensive (conservative) or intensive (profile-preserving). For more information, see System Coupling's Mapping Capabilities.

4: Transfers of Force Density to Mechanical are not supported for System Coupling in Workbench or cases where Mechanical uses shells and force is being transferred to both sides of any shell.

5: This is displacement during the current coupling step (that is, since the end of the previous coupling step).

6: Intensive variables of this quantity type are calculated per-unit.

7: For a given source/target pair of regions, if a transfer of quantity type Heat Transfer Coefficient is defined, then a transfer of quantity type Convection Reference Temperature must also be defined, and vice versa.
