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.

Launch Mesher

(Double Click) Mesh

Mapped Face Meshing

(Right Click) Mesh > Insert > Mapped Face Meshing
Set Geometry to both portions of the surface body. You will have to hold down control in the selection process in order to highlight both halves. Click Update.

Circumferential Edge Sizing

(Right Click) Mesh > Insert > Sizing
Set Geometry to both edges of the surface body. You will have to use the edge selection filter and you will have to hold down control in the selection process in order to highlight both halves. Set Type to Number of Divisions, set Number of Divisions to 96 and set Behavior to Hard. Click Update to generate the new mesh.

You should have 18,624 nodes and 18,432 elements.

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". Next, create a named selection for the right half of the outer boundary and call it "farfield2". Lastly, 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.
