*EQUATION
** The stress output S is Cauchy or true stress and strain output E is 
** accumulated strain. For postprocessing purposes (to compare with 
** test data), nominal stress and strain values are needed and we can
** do the following:
** Nodes 3,6,7 (NSET=FACE42) are tied to node 2 in dof 1 so that:
** Nominal stress (dof 1) = RF1 (@ node 2) / Original area (1 x 1 = 1)
** Nominal strain can be requested with the NE output identifier.
