Assignment of characteristics ================================ For these elements of 1D structures, it is necessary to assign geometric characteristics that are complementary to the mesh data. These data are defined with the AFFE_CARA_ELEM command associated with the following factor keywords: * POUTRE Allows you to define and assign the characteristics of the cross section. Supported models: TUYAU_3M, TUYAU_6M * ORIENTATION Allows you to define and assign a generator. Supported models: TUYAU_3M, TUYAU_6M * MASSIF Optional, allows you to define and assign a direction of magnification (necessary only in the case of a ASSE_COMBU behavior law). Supported models: TUYAU_3M, TUYAU_6M
