2.1.2 Dialog Boxes

Dialog boxes are used to perform simple input/output tasks, such as issuing warning and error messages, or asking a question requiring a yes or no answer.

A dialog box is a separate "temporary'' window that appears when FLUENT needs to communicate with you. When a dialog box appears on your screen, you should take care of it before moving on to other tasks. Once you have tended to the dialog box, it will be closed, and then you can continue.

The following sections describe each type of dialog box.

Information Dialog Box


The Information dialog box is used to report some information that FLUENT thinks you should know. Once you have read the information, you can click the OK button to close the dialog box.

Warning Dialog Box


The Warning dialog box is used to warn you of a potential problem and ask you whether or not you want to proceed with the current operation. If you click the OK button, the operation will proceed. If you click the Cancel button, the operation will be canceled.

Error Dialog Box


The Error dialog box is used to alert you of an error that has occurred. Once you have read the error information, you can click the OK button to close the dialog box.

Working Dialog Box


The Working dialog box is displayed when FLUENT is busy performing a task. This is a special dialog box, because it requires no action by you. It is there to let you know that you must wait. When the program is finished, it will close the dialog box automatically. You can, however, abort the task that is being performed by clicking the Cancel button.

Question Dialog Box


The Question dialog box is used to ask you a question that requires a yes or no answer. You can click the appropriate button to answer the question.

Select File Dialog Box (Windows)

File selection on Windows systems is accomplished using the standard Windows Select File dialog box.

Figure 2.1.4: The Select File Dialog Box for Windows

See documentation regarding your Windows system for further instructions on file selection.

Select File Dialog Box (UNIX or Linux)

For UNIX or Linux systems, note that the appearance of the Select File dialog box will not always be the same.

Figure 2.1.5: The Select File Dialog Box for UNIX or Linux Platforms

The version shown in Figure  2.1.5 will appear in almost all cases, but it will be different if you are loading external data files for use in an XY plot (see the Section  28.8.2 for more information). In such cases, the dialog box will look like Figure  2.1.6.

The steps for file selection are as follows:

1.   Go to the appropriate directory. You can do this in two different ways:
  • Enter the path to the desired directory in the Filter text entry box and then press the <Enter> key or click the Filter button. Be sure to include the final / character in the pathname, before the optional search pattern (described below).

  • Double-click a directory, and then a subdirectory, etc. in the Directories list until you reach the directory you want. You can also click once on a directory and then click the Filter button, instead of double-clicking. Note that the " .'' item represents the current directory and the " ..'' item represents the parent directory.

2.   Specify the file name by selecting it in the Files list or entering it in the File text entry box (if available) at the bottom of the dialog box. The name of this text entry box will change depending on the type of file you are selecting ( Case File, Journal File, etc.).


Note that if you are searching for an existing file with a nonstandard extension, you may need to modify the "search pattern'' at the end of the path in the Filter text entry box. For example, if you are reading a data file, the default extension in the search path will be *.dat*, and only those files that have a .dat extension will appear in the Files list. If you want files with a .DAT extension to appear in the Files list, you can change the search pattern to *.DAT*. If you want all files in the directory to be listed in the Files list, enter just * as the search pattern.

3.   If you are reading multiple XY-plot data files, the selected file will be added to the list of XY File(s). You can choose another file, following the instructions above, and it will also be added to this list. (If you accidentally select the wrong file, you can choose it in the XY File(s) list and click the Remove button to remove it from the list of files to be read.) Repeat until all of the desired files are in the XY File(s) list.

4.   If you are writing a case, data, or radiation file, use the Write Binary Files check box to specify whether the file should be written as a text or binary file. You can read and edit a text file, but it will require more storage space than the same file in binary format. Binary files take up less space and can be read and written by FLUENT more quickly.

5.   Click the OK button to read or write the specified file. Shortcuts for this step are as follows:
  • If your file appears in the Files list and you are not reading an XY file, double-click it instead of just selecting it. This will automatically activate the OK button. (If you are reading an XY file, you will always have to click OK yourself. Clicking or double-clicking will just add the selected file to the XY File(s) list.)

  • If you entered the name of the file in the File text entry box, you can press the <Enter> key instead of clicking the OK button.
