** Journal
- journal file :: a sequence of ANSYS Fluent commands
- The purpose of a journal file is to automate a series of commands instead of entering them repeatedly
on the command line.
- the journal file does not contain any response to the confirmation request, ANSYS Fluent cannot
continue to follow the instructions of the journal file.
for more information, refer to Scheme notes file:C:\Users\exw692\Dropbox\Emacs\Scheme.org
The list of instructions can be written within a text editor.
*** record journal GUI
Fluent can also record all what is done during the interactive setup through
File > Write > Start Journal.
The setup is saved with GUI language in the journal file.
But it is recommended to create journal file with the TUI
(using TUI commands or scheme commands) and not through de GUI, as GUI structure may changes from one version to another one.
Note that in this recorded file, all the lines will start with (cx-gui-do ....) which represents all the click on the GUI.
**** note
Be careful not to change the directory while recording a journal file.
**** reference
>> 4.9 Creating and Reading Journal Files, https://www.sharcnet.ca/Software/Fluent6/html/ug/node94.htm#JournalFile
*** The interactive TUI inside Fluent helps:
type commands in the console window of fluent GUI
~>~ #command prompt
~q~ #quit, back up a level
~Enter~ # generate a listing of the submenus and commands in the current menu
**** In batch mode:
[usual fluent starting command] -i journal_file.jou &
For example:
~fluent 3ddp -t4 -i example.jou -g >> transcript.out~
This command will run Fluent in 3d double precision (dp), in parallel on 4 procs (-t4) using the *example.jou* journal file (-i), in batch (-g) and save the output to the transcript.out file (>>).

** Animation/residual/monitor on cluster
The cluster cannot run any graphics, so don’t try to plot any figures.
If you do, errors transpire and you’ll have to delete the job (see Section 3.3).
This includes animations, residuals and monitors.
If you want to make animations, write the data files and use TecPlot on your PC.
Your output file is where you will monitor the convergence of your simulation.
Here is a sample journal file for a 2D simulation I ran in batch mode.

Solution Animation File
If you selected Metafile or PPM Image under Storage Type in the Animation Sequence panel, then FLUENT will save the solution animation file for you automatically. It will be saved in the specified Storage Directory, and its name will be the Name you specified for the sequence, with a .cxa extension (e.g., pressure-contour.cxa). In addition to the .cxa file, FLUENT will also save a metafile with a .hmf extension for each frame (e.g., pressure-contour_0002.hmf). The .cxa file contains a list of the associated .hmf files, and tells FLUENT the order in which to display them.

A command name
consists of phrases separated by hyphens. A command is matched by matching an initial sequence of its phrases. Matching of hyphens is optional
2.2.Text Prompt System
The following shows some examples of prompts:
filled-mesh? [no] Enter
shrink-factor [0.1] Enter
line-weight [1] Enter
title [""]Enter
The default value for a prompt is accepted by pressing Enter on the keyboard or typing a , (comma).
Ctrl+c.#abort a prompt sequence, simply press
’() or () #empty list
terminate the process with an empty list
"~a" stands for random variable, like % in C language.
"()" means that we simply press "enter" and do not specify any names.
"x" at the end of line is the same loop variable and two of "x" correspond to two of "~a".
q, take one level above

** Modifying the View
Select and control the view of the scene that is displayed in the graphics window.
all defined views will be saved in the case file when you write one.
If you plan to use your views with another case file, you can write a “view file” containing just the views.

** discretization schemes
Use the following text commands as appropriate followed by the appropriate number from the list below.
/solve/set/discretization-scheme/pressure
/solve/set/discretization-scheme/flow
/solve/set/discretization-scheme/mom
/solve/set/discretization-scheme/k
/solve/set/discretization-scheme/epsilon
/solve/set/discretization-scheme/temperature
Basic discretization schemes:
("First Order Upwind" . 0)
("Second Order Upwind" . 1)
("Power Law" . 2)
("Central Differencing" . 3)
("QUICK" . 4)
Pressure Discretization:
("Standard" . 10)
("Linear" . 11)
("Second Order" . 12)
("Body Force Weighted" . 13)
("PRESTO!" . 14)
("Continuity Based" . 15)
Pressure-Velocity-Coupling:
("SIMPLE" . 20)
("SIMPLEC" . 21)
("PISO" . 22)
Example 1:
To set pressure-velocity coupling to PISO use the TUI
/solve/set/discretization-scheme/flow 22
Example 2:
To set pressure discretization to Body-Force Weighted use the TUI
/solve/set/discretization-scheme/pressure 13
