(U2.01.09) Analytical definition of a stress field and an initial field of internal variables
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.
