Element Definition Block

    Purpose: Defines the topology of the elements

    1. Record:
    Form: KEY, CODE, FORMAT
    Where: KEY    = 3
           CODE   = C
           FORMAT = Format indicator
                    0 = short format
                    1 = long format
    Format:(1X,'   3','C',67X,I1)

    The following block of records must be repeated for each element:
      The first record initializes an element definition:
      Form: KEY, ELEMENT, TYPE, GROUP, MATERIAL
      Short Format:(1X,'-1',I5,3I5)
      Long Format:(1X,'-1',I10,3I5)
    Where: KEY    = -1
           NODE   = element number
           TYPE   = element type, see section ``Element Types''
           GROUP  = element group number, see command ``groups''
           MATERIAL= element material number, see command ``mats''.

      Then the nodes in the correct order have to follow:
      Form: KEY,NODE,NODE,NODE,NODE, ...
      Short Format:(1X,'-2',15I5)
      Long Format:(1X,'-2',10I10)
    Where: KEY    = -2
           NODE   = node number

    Additional lines must follow if more nodes are used.

    Last Record:
    Form: KEY
    Format:(1X,'-3')
