3 2 Element type 2 1 5 4 3 Element type 6 Figure <strong>2.1</strong>: Triangular elements and their node numbering cubic interpolation seem to be untested, and their node numbering is also uncertain. Probably the node numbering corresponds to the standard given in [3]. Example: *INFEM: SOLID: TOP: S1 ** eletype, material, nodes 5, 1, 8, 7, 6, 5, 1, 2, 3, 4 6, 1, 9, 10, 6, 7, 8, 11, . . . Note! Each line must have the correct number of entries. 19 6 2 1

Each row specifies one material type, as follows, , Thus a typical steel material (in SI-units) is specified by the following example. Example: 20 8 3 2 1
