3. Modeling A

3.1. Characteristics of modeling and meshing

The model is composed of POU_D_TGM (multifibre beams). All sections are in the shape of a \("I"\) and are described with 30 fibers: 1 in the thickness of the core and the soles, 10 in the width of the soles and 10 in the height of the core.

3.2. Tested sizes and results

As already specified in the introduction, all the reference results are of type AUTRE_ASTER obtained with the POU_D_TG modeling.

The table below summarizes the results obtained by the POST_ELEM command, with the MASS_INER keyword.
