1. In Workbench, double-click on Model cell A4.
2. To view the default mesh:
   1. Highlight Mesh in the Project Tree.
   2. Click Update. 
      
3. To make a regular mesh:
   1. Right click on Mesh > Insert > Mapped Face Meshing.
   2. Using the Face Selection Tool, click on the rectangular geometry. Click Geometry > Apply.
   3. Click Update. 
4. To change the element size:
   1. Highlight Mesh in the Project Tree. Right click on Mesh > Insert > Sizing.
   2. Using the Face Selection Tool, click on the rectangular geometry. Click Geometry > Apply.
   3. Next to Element Size, type the following to insert an expression:  = 8/3
   4. Hit Enter. 
5. Save Project. 

For this example, we would like to use "Q4" elements i.e. quadrilateral elements with 4 nodes for every element, one at each corner. It turns out that the quadrilateral elements in the mesh obtained above have mid-side nodes in addition to the corner nodes. So these elements are "Q8" elements with a total of 8 nodes for each element. In the video below, we drop mid-side nodes to get "Q4" elements (in the ANSYS element library, these are referred to as PLANE 182). Note that the mid-side nodes provide higher accuracy, so in the real world, you would not drop mid-side nodes unless you had a compelling reason to do so. Here we do it for learning purposes.
