*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.

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

Required, mutually exclusive parameters: 

EXPORT

Include this parameter to specify fields and the accompanying region for export to the coupled analysis.

IMPORT

Include this parameter to specify fields and the accompanying region for import from the coupled analysis.

Optional parameter:

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.

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,” Section 17.2.1 of the Abaqus Analysis User's Manual.

  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,” Section 17.2.1 of the Abaqus Analysis User's Manual.

  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,” Section 17.2.1 of the Abaqus Analysis User's Manual.

  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.


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

Optional parameter:

TYPE

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

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.


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

Required, mutually exclusive parameters: 

EXPORT

Include this parameter to specify fields and accompanying regions for export to MADYMO.

IMPORT

Include this parameter to specify fields and accompanying regions for import from MADYMO.

Optional parameter:

REGION ID

Integer identifier of the co-simulation region. The default value is 1. MADYMO uses this integer identifier to distinguish one region from another when multiple *CO-SIMULATION REGION options are associated with a single *CO-SIMULATION option.

Data lines to define the co-simulation regions and the fields passed across them: 

First line:

  1. The name of the element-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,” Section 17.2.1 of the Abaqus Analysis User's Manual.

  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 surface or to define additional co-simulation regions and their import or export fields.
