[FAQ]

If we combine a TUI command with Fluent’s Execute Commands we can write out files at specified intervals. The exact command will vary slightly with models, surface labels etc so work through to get the exact syntax.
An example is:
/file/export-to-cfd-post filename_%t surface list () property list () no yes no
The surface list needs each label in ” ” marks, and using * instead should pick all surfaces and volumes.
Note, %t will append the time step (%f is flow time) and () round-brackets terminates a list. Using when in a new menu level will cause Fluent to list all available options at that level, while q (Q) takes you back up one level. The command should then added to the Execute Commands under Calculation Activities and set to trigger every some time steps.
