Item Content JEVEUX ========================= Purpose. PJMNO ------------ In PROJ_MESU_MODAL, this object contains a list of the numbers of the nodes where the sensors are located. A sensor measures the component of the field at a point in a given direction. Multiple sensors can be located at a single node. PJMNO (1): node number associated with sensor number 1 PJMNO (2): node number associated with sensor number 2 ... The useful length (LONUTI) of this object is equal to the number of sensors (nbcapt). If the keywords PROJ_MESU and MODE_MESURE are entered in MACR_ELEM_STAT, the sd_proj_mesu produced by MACR_ELEM_STAT contains the list of external node numbers. And the useful length (LONUTI) is equal to the number of external ddls (nddles) of the macro element. Purpose. PJMRG ------------ In PROJ_MESU_MODAL, this object contains the name of the sensor's sensitive component: 'DX', 'DY', 'DZ', 'DZ', 'D1', 'D2', 'D3',... 'D1', 'D2', 'D3' are the directions defined when reading the data measured by LIRE_RESU on the 58 datasets (U7.02.01). In MACR_ELEM_STAT, it contains the name of the external ddl component. The length of this object is the same as the length of. PJMNO. PJMRG (1): name of the component associated with sensor 1 (or name of the external ddl component 1) PJMRG (2): name of the component associated with sensor 2 (or name of the external ddl 2 component) ...

PJMBP (LONUTI): projection of the first vector of the base onto the component PJMRG (LONUTI) from node PJMNO (LONUTI) PJMBP (LONUTI +1): projection of the 2nd vector of the base onto the component PJMRG (1) from node PJMNO (1) ... PJMBP (LONUTI *nbmode): projection of the nbmode-th vector of the base onto the component PJMRG (LONUTI) of node PJMNO (LONUTI) Purpose. PJMRF ------------ This object contains the names of the concepts used: PJMRF (1): name of the "measure" model PJMRF (2): name of the measured field ('DEPL', '', '', 'VITE', 'ACCE', 'SIEF_ *', 'EPSI_*') PJMRF (3): name of the projection base PJMRF (4): name of the concept that contains the identified eigenmodes (keyword argument MODE_MESURE from MACR_ELEM_STAT) PJMRF (5): name of the concept created by PROJ_MESU_MODAL, used for calculating the supermesh (keyword argument PROJ_MESU of MACR_ELEM_STAT). *Note:* PJMRF (4) *and* PJMRF (5) *are not filled in if calculation* PROJ_MESU_MODAL *.* Purpose. PJMOR ------------ This object is only created when calculating with PROJ_MESU_MODAL. It indicates the sensitive direction of the sensor. The length of this object is equal to three times the length of. PJMNO. PJMOR (1): projection along DX of the sensitive direction of sensor number 1 PJMOR (2): projection along DY of the sensitive direction of sensor number 1 PJMOR (3): projection along DZ of the sensitive direction of sensor number 1 PJMOR (4): projection along DX of the sensitive direction of sensor number 2 PJMOR (5): projection along DY of the sensitive direction of sensor number 2 PJMOR (6): projection along DZ of the sensitive direction of sensor number 2 ... Purpose. PJMMM ------------ This item was created only by MACR_ELEM_STAT. It contains the identified specific nbmoidmodes arranged according to the pair. PJMNOet. PJMRGde the sd_proj_me given by PJMRF (5). The length of the vector is nbcapt*nbmoid PJMMM (1) component of the first mode identified along the sensitive direction of sensor 1 PJMMM (2) component of the first mode identified along the sensitive direction of the sensor 2 ...
