10.4. notes

The values are tested automatically using the functionalities offered by procedure POST_RELEVE:

• extraction on the nodes corresponding to the observed points of the mean values of the components \({M}_{\mathit{xx}}\) and \({M}_{\mathit{yy}}\); these values are extracted 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 \({M}_{\mathit{xx}}\), \({M}_{\mathit{yy}}\) and \({M}_{\mathit{rr}}\), \({M}_{\theta \theta }\) data on page 3.
