Step 2: Mesh

1.   Read the mesh file elbow.msh.

File $\rightarrow$ Read $\rightarrow$ Mesh...

  Select Read from the File menu, then select Mesh... to open the Select File dialog box.

(a)   Select the mesh file by clicking elbow.msh in the introduction folder created when you unzipped the original file.

(b)   Click OK to read the file and close the Select File dialog box.

  As the mesh file is read by ANSYS FLUENT, messages will appear in the console reporting the progress of the conversion. ANSYS FLUENT will report that 13,852 hexahedral fluid cells have been read, along with a number of boundary faces with different zone identifiers.

Note:   The mesh is displayed in the graphics window by default.

Extra:   You can use the mouse to probe for mesh information in the graphics window. If you click the right mouse button with the pointer on any node in the mesh, information about the associated zone will be displayed in the console, including the name of the zone.

Alternatively, you can click the probe button ( ) in the graphics toolbar and click the left mouse button on any node. This feature is especially useful when you have several zones of the same type and you want to distinguish between them quickly.

For this 3D problem, you can make it easier to probe particular nodes by changing the view. You can perform any of the actions described in the following table:

Table 1.1: View Manipulation Instructions

Action	Using Default Mouse Button Settings	Using Graphics Toolbar Buttons
Rotate view (vertical, horizontal)	Press the left mouse button and drag the mouse. Release the mouse button when the viewing angle is satisfactory.	After clicking , press the left mouse button and drag the mouse. Dragging side to side rotates the view about the vertical axis, and up and down rotates the view about the horizontal axis.
Roll view (clockwise, counterclockwise)	(not applicable)	After clicking , press the left mouse button and drag the mouse side to side to roll the view clockwise and counterclockwise.
Translate view	Press the middle mouse button once at any point in the display to center the view at that point.	After clicking , press the left mouse button and drag the mouse until the view is satisfactory.
Zoom in on view	Press the middle mouse button and drag the mouse to the right and either up or down. This action will cause a rectangle to appear in the display. When you release the mouse button, a new view will be displayed which consists entirely of the contents of the rectangle.	After clicking , press the left mouse button and drag the mouse to the right and up or down. This action will cause a rectangle to appear in the display. When you release the mouse button, a new view will be displayed which consists entirely of the contents of the rectangle. Alternatively, after clicking , press the left mouse button and drag the mouse up.
Zoom out from view	Press the middle mouse button and drag the mouse to the right and either up or down. This action will cause a rectangle to appear in the display. When you release the mouse button, a new view will be displayed which consists entirely of the contents of the rectangle.	After clicking , press the left mouse button and drag the mouse to the left and up or down. This action will cause a rectangle to appear in the display. When you release the mouse button, the magnification of the view will be reduced by an amount that is inversely proportional to the size of the rectangle. The new view will be centered at the center of the rectangle. Alternatively, after clicking , press the left mouse button and drag the mouse up.

Note:   After you have clicked a button in the graphics toolbar, you can return to the default mouse button settings by clicking .

2.   Manipulate the mesh display to obtain a front view as shown in Figure  1.2.

Graphics and Animations Views...

  Select Graphics and Animations in the navigation pane, then click Views... in the Graphics and Animations task page.

(a)   Select front from the Views selection list.

Note:   A list item is selected if it is highlighted, and deselected if it is not highlighted.

(b)   Click Apply and close the Views dialog box.
