Résumé: It is explained how manufacture two of the fields constituting the initial state of a nonlinear computation (STAT_NON_LINE): the stress field and the field of intern variables.

  • the components of the stress field have an “analytical” form (for example: state of a ground subjected

to the “weight of the grounds”),

  • the components of the field of intern variables are non-zero constants.

In both cases, the solution consists in connecting a certain number of commands CREA_CHAMP.
