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.
