*CO-SIMULATION REGION

Identify the interface regions in the Abaqus model and specify the fields to be exchanged during co-simulation.

This option is used to identify the regions across which data will be exchanged and to specify the fields to be passed across those regions. It must be used in conjunction with the CO-SIMULATION option to identify the analysis program for co-simulation with Abaqus.

Abaqus/CAEInteraction module

Defining a co-simulation region for CO-SIMULATION, PROGRAM=MULTIPHYSICS or PROGRAM=MPCCI

Required, mutually exclusive parameters

EXPORT

When TYPE=NODE, SURFACE, or VOLUME, include this parameter to specify fields and the accompanying region for export to the coupled analysis.

When TYPE=DISCRETE, include this parameter to specify sensor variables for export.

IMPORT

When TYPE=NODE, SURFACE, or VOLUME, include this parameter to specify fields and the accompanying region for import from the coupled analysis.

When TYPE=DISCRETE, include this parameter to specify actuator variables for import.

Optional parameters

TYPE

Set TYPE=NODE to define a co-simulation region consisting of nodes only.

Set TYPE=SURFACE (default) to define a co-simulation surface region.

Set TYPE=VOLUME to define a co-simulation volume region.

Set TYPE=DISCRETE to define coupling through sensors and actuators.

Data lines for TYPE=NODE

First line

  1. The name of the node set.

  2. Field identifier for the field to be passed across this surface. The field identifiers are defined in Preparing an Abaqus analysis for co-simulation.

  3. Etc., up to seven field identifiers.

Repeat this data line as often as necessary to define more than seven field identifiers for a given region. Repeat the option to define import and/or export fields. When PROGRAM=MULTIPHYSICS, only a single node set can be declared for the co-simulation.

Data lines for TYPE=SURFACE

First line

  1. The name of the element-based or node-based surface.

  2. Field identifier for the field to be passed across this surface. The field identifiers are defined in Preparing an Abaqus analysis for co-simulation.

  3. Etc., up to seven field identifiers.

Repeat this data line as often as necessary to define more than seven field identifiers for a given region. Repeat the option to define import and/or export fields. When PROGRAM=MULTIPHYSICS, only a single surface can be declared for the co-simulation.

Data lines for TYPE=VOLUME

First line

  1. The name of the element set.

  2. Field identifier for the field to be passed across this surface. The field identifiers are defined in Preparing an Abaqus analysis for co-simulation.

  3. Etc., up to seven field identifiers.

Repeat this data line as often as necessary to define more than seven field identifiers for a given region. Repeat the option to define import and/or export fields. When PROGRAM=MULTIPHYSICS, only a single element set can be declared for the co-simulation.

Data lines for TYPE=DISCRETE

First line

  1. The name of the first sensor or actuator.

  2. The name of the second sensor or actuator.

  3. Etc., up to seven sensor or actuator identifiers.

Repeat this data line as often as necessary to define more than seven sensor or actuator definitions. The data line can refer either to names of sensors only or to names of actuators only, according to the IMPORT or EXPORT parameter setting.

Defining a co-simulation region for CO-SIMULATION, PROGRAM=ABAQUS

Set TYPE=NODE to define a co-simulation region using a node set.

Data line for TYPE=SURFACE

First (and only) line

  1. The name of the element-based or node-based surface.

Data line for TYPE=NODE

First (and only) line

  1. The name of the node set.
