If you would prefer to skip the geometry and mesh steps, then you can download the necessary files here. Download the "zip" file, then extract the files to your working directory. In order to load the necessary files, go to the Workbench Project Page, then (Click) File > Open > "Cylinder.wbpj". Lastly, click here to skip ahead to Step 4 of the tutorial. |
2. Geometry
Fluid Flow(FLUENT) Project Selection
Drag Fluid Flow(FLUENT) into the Project Schematic window.
Analysis Type
(Right Click) Geometry > Properties
Set Analysis Type to 2D
Launch Design Modeler
(Double Click) Geometry
Create Two Concentric Circles and Dimension
Create two concentric circles, centered around the origin in the xy plane. Set the diameter of the inner circle to 1m and set the diameter of the outer circle to 64 m.
Surface Body Creation
Concept > Surfaces From Sketches.
Set the Base Object to Sketch 1 (located underneath XYPlane in the Tree). Click Generate
Create a Bisecting Line
Click on XYPlane in the tree and it should highlight blue. Then, click the new sketch button, 
. In the new sketch draw a line on the y axis that goes through both of the concentric circles. Make sure that it is coincident to the y axis. Then trim the line segments that lay inside of the inner circle and the line segments that lay outside of the outer circle. This, is carried out by using the Trim feature located in the Modify portion of Sketching.
Line Body Creation
Concept > Lines From Sketches.
Set the Base Object to Sketch 2 (located underneath XYPlane in the Tree). Click Generate
Projection
Tools > Projection.
Apply the two lines that you created to edge and apply the surface body to target. You must do these steps by using the line selection filter and the surface selection filter. For the two lines hold down control to select them both. Click Generate.
