Once participant physics and coupling setups are complete, generate the solver input file and, where applicable, the System Coupling Participant (.scp) setup file for each participant. The folder containing the file used to add a participant to a coupled analysis is designated as that participant's working directory, so you will generally write these files to the intended working directory for the participant.
For details on how participant working directories may be defined, see WorkingDirectory in the System Coupling Settings and Commands Reference documentation.
- Participant solver input files
After you have finished each participant's setup, generate the solver input file(s) to the participant's working directory before exiting the participant application. Use the method noted in the participant's product documentation.
For details on the types of solver files supported for participants, see the following sections in the System Coupling Settings and Commands Reference documentation:
Fluent participants: FluentInput object
AEDT, CFX, CFD Server, Forte, Mechanical, and Mechanical Server participants: InitialInput setting
- Participant Coupling Setup files
- SCP setup files
The participant setup files needed are determined by how the participant is added (that is, with an input or executable file) and/or the participant type. If an input file is used, participant information may be populated to the data model either directly (from an .scp file) or indirectly (from another file format used by the participant).
If coupling and/or automatic .scp-file generation are enabled for a participant, then the participant automatically generates the .scp file (and any other configuration files needed by System Coupling) at the same time and in the same location as its solver input file.
If automatic .scp-file generation is not enabled for a participant, then you can generate the .scp file on demand using the method noted in the participant's product documentation.
If participant .scp files and participant solver input files are generated when a System Coupling setup is exported from Workbench, then these files are written to the participant working directory, which is created as a subdirectory in the co-simulation working directory specified for the export.
For details on the contents and generation of .scp files, see Participant Setup File.
- Other setup files
Forte, CFD Server, and Mechanical Server participants use their own setup files, as follows:
Forte participants use a Forte solver (.ftsim) file.
CFD Server participants use a CFD surface mesh (.csv) file.
Mechanical Server participants use:
a Mechanical modal analysis results (.rst) file, and
a modal mass (*.mode) file, if defined for the analysis.
