Generate Mesh
After the boundaries are Discretized, select the Generate Mesh 
option from the toolbar or the Mesh menu, and the finite element mesh will be generated.
The mesh will be generated according to the discretization of the boundaries, and the Element Type in the Mesh Setup dialog. The total number of elements and number of nodes in the mesh will be displayed in the Status Bar.
- The Mesh option is also available as a button in the Mesh Setup dialog.
- The Discretize and Mesh option can be used as a shortcut to Discretize and Mesh with a single mouse click.
- After the mesh has been generated, options are available in the Mesh Refinement sub-menu of the Mesh menu, which allow the user to refine or customize any area of the mesh. See the Mesh Refinement topic for details.
- The Reset Mesh option can be used at any time to reset the mesh and/or discretization.
