Mesh

In this section the geometry will be meshed with 18,432 elements. The geometry will be given 192 circumferential divisions and 96 radial divisions. Mapped face meshing will be used and biasing will be used in order to significantly increase the number of elements located close to the cylinder.

Create Named Selections

In this section the various parts of the geometry will be named according to the image below.

First create a named selection for the left half of the outer boundary and call it "farfield1". To create the named selection, choose the edge selection filter ,Then choose the left half of the outer boundary. After the edge is chosen, it should appear to be green. Then right click and select "Create Named Selection". In the new window that appears, type in farfield1 and select "OK" to confirm.

Next, similarly create a named selection for the right half of the outer boundary and call it "farfield2".  Create a named selection for both sides of the inner circle(cylinder) and call it "cylinderwall". When creating the third named selection, make sure that you included both halves of the circle. You will have to hold down control to select both edges.

Lastly, create a named selection for the flow domain. Select the face of the flow domain between the cylinder wall and farfield1 and farfield2 and call it "flowdomain".
