3. Mesh

In the early stages of this tutorial, we ask you to download the mesh and geometry files. In the future the meshing and geometry steps will be fleshed out. Download the necessary files by clicking 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.

Under Construction

The meshing steps underneath this construction banner are currently unfinished. Please download the geometry and meshing files above.

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.

Radial Edge Sizing 1 (Top Half)

(Right Click) Mesh > Insert > Sizing
Set Geometry to the top half of the bisecting line. Set Type to Number of Divisions, set Number of Divisions to 96 and set Behavior to Hard. Then, set Bias Type to the first option and set Bias Factor to 460. These selections are shown in the image below.



Radial Edge Sizing 2 (Bottom Half)

(Right Click) Mesh > Insert > Sizing
Set Geometry to the top half of the bisecting line. Set Type to Number of Divisions, set Number of Divisions to 96 and set Behavior to Hard. Then, set Bias Type to the second option and set Bias Factor to 460. These selections are shown in the image below.



Then, click Update to generate the new mesh. You should obtain the mesh, that is shown below.



Verify Mesh Size

(Click) Mesh > (Expand) Statistics
You should have 18,624 nodes and 18,432 elements.
