ABAQUS Keywords Reference Manual  

*CO-SIMULATION REGION
Identify the interface regions in the ABAQUS model and specify the solution quantities to be exchanged with the third-party program.

This option is used to identify the surfaces comprising the co-simulation interface regions 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 third-party program for co-simulation.

Type: History data

Optional parameter:

REGION ID

Integer identifier of the co-simulation region. The default value is 1. The third-party 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 program.

IMPORT

Include this parameter to specify solution quantities and accompanying regions for import from the third-party 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 13.1.2 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.
