r7.02.17 Determination of an equivalent crack from a damage field

Summary:

The command POST_ENDO_FISS performs post-processing on a result derived from the mechanics of continuous media. The aim is to find the curve that represents the crack from a representative field and the crack opening. The field may be damage or another scalar field. As input, the command uses an evol_noli or cham_gd concept, containing the field to be post-processed. This should be a node field. As output, the command returns the crack mesh, as well as a table containing the coordinates of the crack nodes and the value of the opening on each node. The procedure applies to 2D studies.
