**v6.04.228** SSNV228 — Pre-tensioning a stud
=======================================================

**Summary:**

This test illustrates how to pre-tension a stud in Code_Aster. The methodology adopted consists in applying a relative displacement between a group of elements of the stud and a group of elements of the nut (between the two faces that are normally threaded). Two models are proposed:


* Modeling A: manual determination of the displacement.


* B modeling: automated determination of the displacement using macr_recal.
