214 Chapter 11 Incompressible Flow Analysis

 On the Analysis Systems window, click twice on the Fluid
Flow (Fluent) item. A new small box will appear on the
Project Schematic window.
 Replace the name Fluid Flow (Fluent) in the lower blue tab
by retyping the desired project name, e.g., Lid Driven
Cavity Flow, and hit Enter.
 Right click on the Geometry tab and select the Properties
option, the Properties of Schematic window will open.
Change the Analysis Type under the Advanced Geometry
Options from 3D to 2D. Then, close this window.

(b) Creating Geometry

 On the Project Schematic window, right click on the
Geometry tab and select the New Geometry…. This will
launch the ANSYS Design Modeler (green logo DM).
 On DM window, set unit in the Units menu on the upper
tab to Meter.
 On the Tree Outline window, right click on XYPlane and
select Look at. The X-Y-Z coordinates on the Model View
in 3D view will become X-Y coordinates in 2D view.
 Select the Sketching tab below the Tree Outline window,
the Sketching Toolboxes will pop-up in the same place.
 Select the Settings tab and then Grid, activate the buttons
Show in 2D and Snap. The grid will appear on the main
window. Grid snapping provides convenience when
drawing model.
 Make sure that the Major Grid Spacing is set to 1 m,
Minor-Steps per Major is 1, and Snaps per Minor is 1.
 Enlarge the scale by clicking at the Box Zoom icon on the
upper part of the screen (icon with plus sign on the
magnifying glass) and draw a box with appropriate size to
zoom in. Click it again after finishing.
