For Fluent (with Fluent Meshing) component
systems, you can use a journal file (*.jou) to implement the text user interface (TUI) commands and/or Scheme
expressions related to mesh generation.
To associate the journal file with the Mesh cell:
Right-click the Mesh cell and from the context menu, select Register Update Journal File.
Browse to the journal file location and select the file.
Once the journal file has been associated with the Mesh cell, the Register Update Journal File command is replaced by Unregister Startup Journal File. You can execute this command if you want to disassociate the assigned journal file from the Mesh cell.
On performing Update of the Mesh cell, the registered journal file associated with the cell will be executed in Fluent Meshing in the background.
