*CO-SIMULATION REGION
Identify the interface regions in the Abaqus model and specify the solution quantities to be exchanged during co-simulation.

This option is used to identify the regions across which data will be exchanged and to specify the solution quantities 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.

Products: Abaqus/Standard  Abaqus/Explicit  

Type: History data

Level: Step


Defining a co-simulation region for exchange with a third-party analysis program

This section defines the use of this option when the PROGRAM parameter for the *CO-SIMULATION option is set to any value other than ABAQUS.

References:

Optional parameter:

REGION ID

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

Optional parameters (mutually exclusive—if neither parameter is specified, Abaqus selects the coordinates for export and the concentrated forces for import): 

EXPORT

Include this parameter to specify solution quantities and accompanying regions for export to the third-party analysis program.

IMPORT

Include this parameter to specify solution quantities and accompanying regions for import from the third-party analysis program.

Data lines to define the co-simulation regions and the solution quantities passed across them if the EXPORT or IMPORT parameter is included: 

First line:

  1. The name of the element-based surface.

  2. Quantity identifier for the solution quantity to be passed across this surface. The quantity identifiers are defined in Preparing an Abaqus analysis for co-simulation, Section 14.1.2 of the Abaqus Analysis User's Manual.

  3. Etc., up to seven quantity identifiers.

Repeat this data line as often as necessary to define more than seven quantity identifiers for a given surface or to define additional co-simulation regions and their import or export solution quantities.


Defining a co-simulation region for exchange with another Abaqus analysis

This section defines the use of this option for Abaqus/Standard to Abaqus/Explicit co-simulation (*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.
