I want to apply pretensioned force in one of my element in the model. So suggest me how do we do that?

Dirk Munro

I think in general, in the input deck it would be done with

*INITIAL CONDITION, TYPE=STRESS

(see manual for element- and material-point-wise input)

or with SIGINI subroutine, which is activated by

*INITIAL CONDITION, TYPE=STRESS, USER

in the input deck.

There are also dedicated options pertaining to pretension / bolt loads associated with `connector elements' in particular.
