• N:M mapping (that is, mapping between different numbers of regions on source and on target)
• Mapping of variables with different properties:
  • Mapping between element-based and node-based variables
  • Mapping between intensive and extensive variables
• Debugging tools
  • Mesh validity checks
  • Code tracer and log output
  • Standalone mode for co-simulation
• EnSight results writing [3]
• Support for MPI parallel processing [4]
• Languages supported [5]
  • C++
  • C
  • Fortran
  • Python
• Support for streaming transcript file to System Coupling GUI for co-simulation [2]

[1] Currently only supported in C++ and Python.

[2] Not currently supported in Fortran.

[3] EnSight results can be written by the participant library only if the mapping workflow is used.

[4] For details, see Execution in a parallel environment.

[5] For details, see Compiling, linking, and executing applications that use the Participant Library.

Note the following limitations:

• Currently, all values are assumed to be in SI units.
• Currently, mapping across multiple applications is only supported via C++ APIs.
