Launch of the macro command CALC_ESSAI, which makes it possible to launch identification and expansion calculations on wireframe structures and to launch structural modification calculations:


* expansion of experimental data based on numerical deformations, using the macro-command MACRO_EXPANS (which performs the elementary operations EXTR_MODE, PROJ_MESU_MODAL, REST_GENE_PHYS and PROJ_CHAMP),


*identification of efforts on any structure, with decomposition of the movement on a modal basis and*a priori* location of the loads,


* structural modification: evaluate the effect of a modification knowing the experimental modal model of the initial structure and the finite element model of the modification made
