Separate to the items listed above, there are known caveats and limitations with the export of data from Fluent to EnSight format. These are captured in the Fluent Documentation. Presented below are a list of the currently known items, and their reference into the online Fluent Documentation:
Changing Cell Zone Transient Datasets
Important: If the files that are exported during multiple transient simulations are to be used as a set, you should run all of the simulations on the same platform, using the same number of processors. This ensures that all of the files are compatible with each other.
Note: If you selected EnSight Case Gold from the File Type drop-down list, Ansys Fluent does not support exporting data files to EnSight during a transient calculation in which a new cell zone or surface is created after the calculation has begun (as can be the case for an in-cylinder simulation, for example).
EnSight Encas File Name
Important: If you do not specify an EnSight Encas File Name, you will have to manually create an appropriate .encas file.
Creating Automatic Export Definitions for Transient Particle History Data
Exporting Particle Data
Important: If you plan to export particle data to EnSight, you should first verify that you have already written the files associated with the EnSight Case Gold file type by using the File/Export/Solution Data... ribbon tab option.
User Defined Surfaces/Created Surfaces
Note: Data on user defined/created surfaces is not available for export to EnSight Case Gold file format.
Important: For non-stationary reference zones, all the velocities are exported to EnSight as velocities relative to the selected reference zone. See the informational note in Data Explorer Files for further details. Ansys Fluent supports exporting polyhedral data to EnSight.
Stationary/Rotating Zone
Important: When you are exporting data for Data Explorer, EnSight Case Gold, or I-deas Universal and the reference zone is not a stationary zone, the data in the velocity fields is exported by default as velocities relative to the motion specification of that zone. This data is always exported, even if you do not choose to export any scalars. Any velocities that you select to export as scalars in the Quantities list (for example, X Velocity, Y Velocity, Radial Velocity, and so on) are exported as absolute velocities. For all other types of exported files, the velocities exported by default are absolute velocities.
Exporting Pathlines
If you plan to write the pathline data in EnSight format, you should first verify that you have already written the files associated with the EnSight Case Gold file type by using the File/Export... ribbon tab option.
