Assign size to surfaces

Now we are going to set a specific mesh size to the triangular surface resulting from the section of one of the vertexes of the prism (surface number 1).

• To detect the surface one the Label option can be chosen, but also the Signal one (see Signal).
• Select Mesh->Unstructured->Assign sizes on surfaces. In the window that appears, enter the size of the elements to be assigned on the surfaces that will be chosen. Enter 0.5 and click Assign.
• Select surface number 1, press <Esc> and Close the window.
• Generate again the mesh with the same general mesh size.
• This results in a high concentration of elements on the chosen surface due to the value selected (0.5).
