Enables you to append the mesh files. This command is available only after a mesh file has been read in.

Append Rules:

Enables you to append the mesh files using the tmerge utility. This command is available only after a mesh file has been read in.

Answering yes will set the Common Fluids Format (CFF) as the default file format for reading and writing case/data files.

Controls whether attempts to overwrite existing files require confirmation.

If you do not want Ansys Fluent to ask you for confirmation before it overwrites existing files, you can enter the file/confirm-overwrite? text command and answer no.

Enables/disables the writing of binary files.

Lists the names of the converters that are used to change foreign mesh (while importing mesh files from third-party packages) files.

Enables you to change the extension (such as .cas, .msh, .neu) and arguments used with a specified filter.

For example, if you saved the PATRAN files with a .NEU extension instead of .neu, you can substitute or add .NEU to the extension list. For some filters, one of the arguments will be the dimensionality of the grid.

When you use the filter-options command for such a filter, you will see a default dimensionality argument of -d a. The dimension will automatically be determined, so you need not substitute 2 or 3 for a.

Enables you to import mesh information generated by some CAD packages (Ansys, I-deas, NASTRAN, PATRAN, and HYPERMESH), as well as mesh information in the CGNS (CFD general notation system) format.

These files are imported using the associated text commands listed here:

Loads the Ansys ACT tool.

Enables you to read a boundary mesh. If the boundary mesh is contained in two or more separate files, you can read them in together and assemble the complete boundary mesh.

This option is also convenient if you want to reuse the boundary mesh from a file containing a large volume mesh.

Enables you to read the mesh contained in a case file.

Case files containing polyhedral cells can also be read in the meshing mode of Fluent. You can display the polyhedral mesh, perform certain mesh manipulation operations, check the mesh quality, and so on.

Enables you to read domain files.

Each mesh file written by Fluent has a domain section. A domain file is the domain section of the mesh file and is written as a separate file. It contains a list of node, face, and cell zone IDs that make up each domain in the mesh.

If a domain that is being read already exists in the mesh, a warning message is displayed. Fluent verifies if the zones defining the domains exist in the mesh. If not, it will display a warning message.

Enables you to read a journal file into the program.

The read-journal command always loads the file in the main (that is, top-level) menu, regardless of where you are in the menu hierarchy when you invoke it.

Enables you to read a mesh file. You can also use this command to read a Fluent mesh file created with GAMBIT, or to read the mesh available in a Fluent case file.

Case files containing polyhedral cells can also be read in the meshing mode of Fluent. You can display the polyhedral mesh, perform certain mesh manipulation operations, check the mesh quality, and so on.

Uses the tmerge utility to read the mesh contained in two or more separate files. It enables you to read the mesh files together and helps assemble the complete mesh.

Enables you to read multiple boundary mesh files into the meshing mode.

Enables you to read in two or more files together and have the complete mesh assembled for you, if the mesh files are contained in two or more separate files.

For example, if you are going to create a hybrid mesh by reading in a triangular boundary mesh and a volume mesh consisting of hexahedral cells, you can read both files at the same time using this command.

Enables you to set the following options for reading mesh files:

Enables you to read in a size field file.

Allows you to set an idle timeout so that an idle Ansys Fluent session will automatically save and close after the specified time.

Allows you to improve backwards compatibility for journal files. This command hides any new TUI prompts that are added at a future release of Ansys Fluent and reverts to the arguments of the release that you specify using the command (within two full releases of the current release). The command is automatically added to a journal file as soon as you start the recording. See Creating and Reading Journal Files for details.

Displays the current release and version information.

Starts recording all input and writes it to a file. The current Fluent version is automatically recorded in the journal file. Note that commands entered using paths from older versions of Fluent will be upgraded to their current path in the journal file. See Creating and Reading Journal Files in the Fluent User's Guide.

To start the journaling process use the file/start-journal command, and end it with the file/stop-journal command (or by exiting the program). To read a journal file into the program, use the file/read-journal command.

The standard period (.) alias is the same as the file/read-journal definition and is defined by:

 (alias ’. (lambda () (ti-read-journal))) 

Starts recording input and output in a file.

A transcript file contains a complete record of all standard input to and output from Fluent (usually all keyboard and user interface input and all screen output).Start the transcription process with the file/start-transcript command, and end it with the file/stop- transcript command (or by exiting the program).

Stops recording input and closes the journal file.

Stops recording input and output, and closes the transcript file.

Enables you to write the specified boundaries into a mesh file.

This is useful for large cases where you may want to mesh different parts of the mesh separately and then merge them together. This enables you to avoid frequent switching between domains for such cases. You can write out selected boundaries to a mesh file and then create the volume mesh for the part in a separate session. You can then read the saved mesh into the previous session and merge the part with the rest of the mesh.

Enables you to write a case file that can be read by Fluent.

Enables you to write all the mesh domains (except global) into a file that can be read.

Enables you to write a mesh file.

Allows you to enable or disable the enforce mesh topology option, modify the compression level, and enable or disable combined continuous zones when writing mesh/case files.

The enforce mesh topology option is enabled by default; where it will orient the face zones consistently when the mesh file is written. If necessary, the zones will be separated, such that each boundary face zone has at most two cell zones as neighbors, one on either side. Also, internal face zones will be inserted between neighboring cell zones that are connected by interior faces.

When writing .msh.h5 files you can modify the compression level and choose whether or not to combine continuous zones. A number between 0 and 9 can be specified for the compression level, with higher values resulting in a better compression ratio, however, will increase the write time. A value of 0 will result in no compression, while a value of 9 provides the best compression ratio and the slowest write speed. When yes is entered for combine continuous zones, all zone data will be combined into one continuous dataset which will reduce file size. However, combining zones can potentially cause a decrease in write and read speed and potentially decreased performance.

Enables you to write a size field file.
