[1] Not currently supported in Fortran.

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

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

[4] 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.
