  Hello.
  Im supposed to plot the longitudial stress at A against mesh density (and the exercise says: the mesh density is measured by n, the number of elements along the side of each geometrical area, and should be plotted logarithmically, in base 2). Im also supposed to do the analysis with both 4- and 8 noded quadrilaterals.

  Also: How do i "choose" 4- and 8 noded quadrilaterals? Quadrilaterals is OK, bus the exercise also says: This section requires four analyses. Initially create a coarse mesh with only one element in each geometrical area. Then analyse the problem three more times, each time successively doubling the mesh density (which will give a total of 12, 48 and 192 elements respectively). Do this with four noded and repeat with eight noded quads.
