Element output

The relative displacements corresponding to the forces below are chosen by requesting the corresponding “strains.” Elastic and plastic strains are available.

Two-dimensional elements

S11	Force per unit length in the first local direction.

S22	Force per unit length in the second local direction.

Three-dimensional elements

S11	Force per unit length in the first local direction.

S22	Force per unit length in the second local direction.

S33	Force per unit length in the third local direction.
