Create Radius of Influence

Now we can proceed to create the geometry for radius of influence. Since both the cylinder and radius of influence is of same shape. We can create the radius of influence by copying and scaling up the cylinder.

Operation Toolpad > Geometry Command Button Image Modified > Edge Command Button Image Modified > Move/Copy Edges Image Modified
Select the cylinder edges. Make sure that the Copy is checked. Under Operation, select Scale. Next to Factor, enter a value of 4. This means that the radius of influence we create will be 4 times the size of the cylinder.

The current geometry should look like this:

Create Farfield Boundaries

Create Upstream Boundary

We will first create the semi-circle upstream boundary. 

Operation Toolpad > Geometry Command Button Image Modified > Edge Command Button Image Modified > Create Edge Image Modified > Arc Image Modified > Image Modified

Input the following data and click Apply.

Radius

Start Angle

90

End Angle

-90

Create Downstream Boundaries

In creating downstream boundaries, we will use bottom up approach where we first create vertices and join the vertices to form edges.

Create vertices with following coordinates:

Operation Toolpad > Geometry Command Button Image Modified > Vertex Command Button Image Modified > Create Vertex Image Modified

Create the vertices by entering the coordinates under Global.

Click the FIT TO WINDOW button to scale the display so that you can see all the vertices.

Connect AB, BC and CD to form three edges.
