• Point cloud is only supported for standalone mapping when mapping intensive variable from volume mesh or point cloud region to volume point cloud region, or surface point cloud region to surface point cloud region.

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

*** For details, see Execution in a Parallel Environment.

**** For details, see Compiling, Linking, and Executing Applications That Use the Participant Library.

***** Not currently supported in Fortran

Note the following limitations:

• Currently, all values are assumed to be in SI units.
• Currently, re-meshing and mesh re-partitioning are not supported in the participant library (however, mesh deformation is supported).
