Region (object)

Define the region's settings.

Each region object has a participant-specified name that System Coupling uses to identify the region object. Region object names must be unique within the analysis, must be in ASCII format, and cannot include forward slashes (/).


Tip:  Shown in the GUI as the Coupling Participant | Region branch.


*DisplayName (setting)

Region name to be displayed in user-facing communications.

Each region object's display name is used, when available, and is shown in System Coupling's GUI, Transcript/Log files, and EnSight-formatted results.


Tip:  Shown in the GUI as the region object under the Region branch.


Topology (setting)

Type of data being transferred from/to the region.

Possible values:

  • Surface

    Available for participants with Dimension set to 2D or 3D.

  • Volume

    Available for participants with Dimension set to 3D.

  • Undefined

    Available for FMU participants.


Tip:  Shown in the GUI as the Coupling Participant | Region | Topology setting.


InputVariables (setting)

Variables for which the region can receive data.

Blank values are permitted.


Tip:  Shown in the GUI as the Coupling Participant | Region | Input Variables setting.


OutputVariables (setting)

Variables for which the region can send data.

Blank values are permitted.


Tip:  Shown in the GUI as the Coupling Participant | Region | Output Variables setting.


RegionDiscretizationType (setting)

Type of discretization being performed on the region.

Possible values:

  • Mesh Region (default value)

    Supports nodes and mesh connectivity such as node to cell, node to face, and face to cell connectivity information.

  • Point Cloud Region

    Supports standalone mapping and co-simulation of intensive variables between regions of like topology. These include:

    • 2D Surface Point Cloud to/from 2D Surface Point Cloud

    • 2D Surface Point Cloud to/from 2D Surface Mesh

    • 3D Surface Point Cloud to/from 3D Surface Point Cloud

    • 3D Surface Point Cloud to/from 3D Surface Mesh

    • 3D Volume Point Cloud to/from 3D Volume Point Cloud

    • 3D Volume Point Cloud to/from 3D Volume Mesh


Tip:  Shown in the GUI as the Coupling Participant | Region | Region Discretization Type setting.
