To create a slab finite element mesh, use the following procedure.

1. Select the Parametric Models tool in the Plate group on the Geometry ribbon tab.
   
   The Parametric Models dialog opens. The structure is displayed as a series of dashed lines to signify this mode can be used to experiment with various settings.
2. Click Add in the Parametric Models dialog. The mouse pointer changes to the add surface cursor .
3. Click the corner nodes of the slab in a clockwise order, clicking on the first node selected to complete the boundary definition.
   
   The Mesh Parameters dialog opens.
4. Specify the parametric model parameters:
   
   1. (Optional) Type a Name for the slab mesh. For example, Meshed Slab.
   2. Select Slab from the Type drop-down list. You may leave the Sub Type as "Undefined" for this example.
   3. Select Triangular as the Meshing Type.
   4. Select Optimize as the Boundary Connectivity.
   5. Type a Target element size of 100 (in).
5. Click OK. The preliminary mesh is displayed in the view window. The mesh parameters are displayed in the Parametric Models dialog.
6. In the Parametric Models dialog, select the Meshed Slab [Slab] entry and then click Merge Mesh.
