$$$$ INCL NOTICE CHAT 11/09/12 21:16:33 7124 DATE 11/09/12 Operateur INCLUSION Voir aussi : ------------------- GEO1 = 'INCLUS' GEO2 GEO3 ('VOLU') | ('STRI') | ('NOID') (FLOT1) ; | ('LARG') | | ('BARY') | Description : _____________ Two cases are to be considered. 2D or 3D plane surfaces : The INCLUS operator extracts the set of elements that are strictly located inside the contour of the GEO3 object (MAILLAGE type) from the GEO2 object (MAILLAGE type). If the option word 'BARY' is used, the element will be selected if its barycenter is inside the contour. If the word 'STRI'ctly is used, all the nodes on the boundary are set to be outside the contour. Otherwise (with the default 'LARG'ely option), they are set to be inside. 3D massive (key-word 'VOLU', placed before other key-words): The INCLUS operator extracts the set of elements that are located inside the volume of the volumic elements of GEO3 object (MAILLAGE type). If the option 'STRI' is used, all the nodes of an element must be inside the volume while if the option 'LARG' is used, to have one node of an element inside the volume is enough to declare the element inside the volume. With the 'BARY' option, an element is inside the volume if its barycenter is inside this volume. The default option is 'STRI'. The generated object GEO1 is of MAILLAGE type. The operator generates an error if the inclusion is empty, except in the presence of the key-word 'NOID', in which case GEO1 is an empty mesh. FLOT1 is NOT used in 2D. In 3D, FLOT1 (FLOTTANT type, i.e. a real) enables to set if a node is inside an element or not according to a criterion of precision. Depending on the sign of FLOT1, one can catch some nodes of GEO2 lightly outside GEO3 (FLOT1>0) or keep only the nodes strictly inside GEO3 (FLOT1<0). By default, FLOT1 is equal to 1.E-2. $$$$
