Assignment on surfaces

1. Select Meshing Assign sizes Surfaces. In the window that comes up, enter the size of the elements to be assigned on the surfaces that will be chosen. Enter 0,5 and click OK.

2. Select the triangular surface resulting from the section of one of the vertexes of the prism. Press ESC.

3. Select Meshing Generate.

4. A window comes up asking if the previous mesh should be eliminated. Click Yes.

5. Another window appears in which you may enter the maximum element size. Leave the default value unaltered and click OK. This results in a high concentration of elements on the chosen surface, given their selected size (0,5). (See Figure 7.)
