Assign structured size

In this section, structured size is assigned to a line. When assigning structured sizes, the exact number of divisions is set, instead of the size of the elements.

Select Mesh->Structured->Lines->Assign number of divisions.
Enter 2 number of divisions in the appearing window, and assign it to the line number 41.
Press <Esc> to indicate that the selection of lines is finished, and Close the window.
You can check graphically the number of structured divisions assigned to the entities using the Mesh->Draw->Num of divisions.
Then generate the mesh again with the same general mesh size as before.
This resulting mesh has only 2 linear elements in line 41, as it can be seen in the figure.
