*CO-SIMULATION
Identify the analysis program for co-simulation with Abaqus.

This option is used to identify the analysis program for co-simulation with Abaqus and to define parameters that control the co-simulation.

Products: Abaqus/Standard  Abaqus/Explicit  Abaqus/CFD  Abaqus/CAE  

Type: History data

Level: Step

Abaqus/CAE: Interaction module

Required parameters:

CONTROLS

Set this parameter equal to the name of the co-simulation controls to be used to define the rendezvousing scheme. This parameter is not valid for PROGRAM=MADYMO.

NAME

Set this parameter equal to a label that will be used to refer to the co-simulation event. The co-simulation name adheres to the naming convention for labels (see “Input syntax rules,” Section 1.2.1 of the Abaqus Analysis User's Manual), except that it cannot begin with a number.

PROGRAM

Set PROGRAM=MULTIPHYSICS for exchange of data between Abaqus and the SIMULIA Co-Simulation Engine, which in turn can exchange data with third-party analysis programs that support the SIMULIA Co-Simulation Engine. This parameter should also be used in an Abaqus/CFD to Abaqus/Standard or Abaqus/CFD to Abaqus/Explicit co-simulation.

Set PROGRAM=ABAQUS for exchange of data with another Abaqus analysis in an Abaqus/Standard to Abaqus/Explicit co-simulation.

Set PROGRAM=DCI for exchange of data between Abaqus and certain third-party analysis programs. Consult the User's Guide for the third-party analysis program to determine when this option is applicable.

Set PROGRAM=MADYMO for exchange of data between Abaqus/Explicit and the occupant simulation program MADYMO.

Set PROGRAM=MPCCI for exchange of data between Abaqus and the Mesh-based parallel Code Coupling Interface (MpCCI), which in turn can exchange data with third-party analysis programs supporting MpCCI.

There are no data lines associated with this option if PROGRAM=MULTIPHYSICS, PROGRAM=ABAQUS, PROGRAM=DCI, or PROGRAM=MPCCI is specified. 

Data line to define the conversion factors for the physical units of mass, length, and time if PROGRAM=MADYMO and the unit system in the Abaqus/Explicit model is different than the unit system in the MADYMO model: 

First (and only) line:

  1. Conversion factor for the mass unit used in the Abaqus model to that in the MADYMO model.

  2. Conversion factor for the length unit used in the Abaqus model to that in the MADYMO model.

  3. Conversion factor for the time unit used in the Abaqus model to that in the MADYMO model.

For example, Abaqus/Explicit will multiply the coordinate values by the above length conversion factor prior to exporting these values to MADYMO. Appropriate scale factors based on the above conversion factors are used for the various quantities that are exported to MADYMO. Similarly, Abaqus will divide the imported values from MADYMO with appropriate scale factors based on the above conversion factors.
