You can create lines and rakes in the domain for releasing particles, obtaining data for comparison with tunnel data, etc. A rake consists of a specified number of points equally spaced
between two specified endpoints.
A line is simply a line that extends up to and includes the specified endpoints; data points will be located where the line intersects the faces of the cell, and consequently may not be equally spaced.
To create a line or rake surface, you will use the
Line/Rake Surface panel (Figure
Figure 27.5.1: The
Line/Rake Surface Panel
The steps for creating the line or rake surface are as follows:
Indicate whether you are creating a
Line surface or a
Rake surface by selecting the appropriate item in the
Type drop-down list.
If you are creating a rake surface, specify the
Number of Points to be equally spaced between the two endpoints.
Specify the location of the line or rake surface. There are three different ways to define the location:
- Enter the coordinates of the first point (
x0,y0,z0) and the last point (
- Click on the
Select Points With Mouse button and then select the endpoints by clicking on locations in the active graphics window with the mouse-probe button. (See Section
28.3 for information about setting mouse button functions.)
- Use the
option to interactively position a line in the graphics window. You can set the initial location of this line using one of the two methods described above for specifying endpoints (or you can start from the position defined by the default
End Points). See Section
27.5.1 for information about using the line tool.
Note that the coordinates of the
End Points will be updated automatically when you use the second or third method described above.
If you do not want to use the default name assigned to the surface, enter a new name under
New Surface Name. The default name is the concatenation of the surface type and an integer which is the new surface ID (e.g.,
rake-6). (If the
New Surface Name you enter is the same as the name of a surface that already exists,
FLUENT will automatically assign the default name to the new surface when it is created.)
| The surface name that you enter must begin with an alphabetical letter. If your surface name begins with any other character or number,
FLUENT will not accept the entry.
Click on the
Create button to create the new surface.
If you want to check that your new surface has been added to the list of all defined surfaces, or you want to delete or otherwise manipulate any surfaces, click on the
Manage... button to open the
Surfaces panel. See Section
27.11 for details.
