g) Repeat Steps (a) through (e) again, using the remaining internal face to split the three-pipe volume. GAMBIT will create three volumes that are connected with common geometry. The decomposed geometry is shown in Figure 3-10 and is now ready to be meshed.

MODELING A THREE-PIPE INTERSECTION (3-D) Procedure © Fluent Inc., Sep-04 3-19 Step 4: Journal Files ! Note that this step is not an essential part of the tutorial and is designed to provide information on using journal files in GAMBIT . Every time a GUI operation is performed in GAMBIT , the corresponding commands are automatically written to a journal file. This journal file, therefore, provides a backup copy of all the commands for the current session. Journal files can be used to recreate a geometry or mesh that was created in a previous session. You can view, run, and edit journal files in GAMBIT . See the GAMBIT User’s Guide for more information on journal files. 1. View the journal file for the current GAMBIT session. File Run Journal… This command sequence opens the Run Journal form. a) Select the Edit / Run Mode option at the top of the form. b) Click the Current Journal button. The File Name for the current journal file will appear in the form. c) Click Accept . This action opens the Edit/Run Journal form. You can see the journal file for the current session, showing every step completed.

GAMBIT will open a new line where you can type a command. b) Type reset in the new line. ! If you run the journal file without executing the reset command, GAMBIT creates new geometry on top of the existing geometry. 3. Save the journal file with a new name. a) In the File Name text entry box at the bottom of the form, delete the text GAMBIT.#####/jou ”. ##### is the process identifier for the current GAMBIT session. In the above form, ##### is 1283 . b) Rename the journal file by typing 3pipe.geo in the File Name text entry box.

By saving the journal file to another name, you ensure that it will not be overwritten or appended. 4. Replay the steps you have taken in the current session. a) Hold down the right mouse button in the TEXT EDIT FIELD (this name will be dis- played in the Description window when the mouse cursor is over this field) of the Edit/Run Journal form until a menu appears. Choose the Select All option in the menu. A black box in the LINE EXECUTION COLUMN of the Edit/Run Journal form indicates that a line is selected. Note that all lines are now marked with a black box. You can select/unselect individual lines by clicking the left mouse button on the arrow on the left side of the required line.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
