7.  Mesh the area.

The next step is to specify mesh controls in order to obtain a particular mesh density.

  1. Main Menu:  Preprocessor
         Mesh Tool
  2. Set global size controls 
  3. Enter 0.25 for element edge length 
  4. OK 
  5. Mesh 
  6. Pick All (in picking menu)
  7. Close 

Results so far

  1. Close Mesh Tool 
  2. Toolbar:  SAVE_DB

In designing this problem, the maximum node limit of ANSYS/ED was taken into consideration.  That is why the 4-node PLANE42 element, rather than the 8-node PLANE82 element was used.  Note that the mesh contains a PLANE42 triangle, which results in a warning.  If you are not using ANSYS/ED, you may use PLANE82 during the element definitions to avoid this message.  Note however that PLANE82 does not work unless you get rid of the Global Element edge length (which was set to 0.25).

Note:  The mesh you see on your screen may vary slightly from the mesh shown above.  As a result of this, you may see slightly different results during postprocessing.  For a discussion of results accuracy, see Chapter 2 of the ANSYS Modeling and Meshing Guide.
