In the step, we'll discretize or chop up the domain to create a mesh containing many "elements". During the numerical solution, ANSYS will obtain a discrete version of our boundary value problem on this mesh. We will generate a regular face mesh with 200 elements. The horizontal edges will have 10 divisions and the vertical edges will have 20 divisions.
ANSYS Mechanical is the application where we'll generate a mesh, apply the material properties and boundary conditions, and obtain a numerical solution to our boundary value problem. In order to start ANSYS Mechanical (Double Click) Model, .
We will create a nice, regular mesh which is done using the "mapped face mesh" option. A mapped face mesh is a mesh that can be mapped to a rectangular domain, hence the name. Our domain is already rectangular, thus mapped faced meshing will yield a rectangular grid as the mesh.
First (Click) Mesh, in the model tree. Next, (Click) Mesh Control > Mapped Face Meshing, as shown below.

Let's specify the number of divisions to be used along each edge rather than have ANSYS pick them automatically. ANSYS calls this step "edge sizing". We will use 20 divisions along the vertical edges and 10 divisions along the horizontal edges. We will work with the horizontal edge first. In order to implement the edge sizing, first (Click) Mesh, . Next, (Click) Mesh Control > Sizing, as shown below.
