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: POU_D_TG, POU_D_TGM

**•** **ORIENTATION**

Allows you to define and assign the orientation of the main axes of inertia around the neutral fiber.

Supported models: POU_D_TG, POU_D_TGM
