Notes:

The value test is performed automatically using the functionalities offered by the procedure POST_RELEVE :

• extraction on the nodes corresponding to the observed points of the observed points of the mean values of the components

  

and

; these values are taken from the field “ EFGE_ELNO “ , and the average is calculated for all the values available on the cells that contain the observed node,

• calculation of the deviation from the reference value provided by applying the correspondence rules between

  

,

and

Contents of the results file

Values at the observation points of the movements and averaged moments.

We also test the continuity of fields EPSI_ELGA and EPSI_ELNO between layers (non-regression tests). In fact, the value calculated at level SUP of the N layer is equal to the value calculated at the INF level of the COUCHE N+1.
