4. B modeling

4.1. Characteristics of modeling and meshing

Same characteristics as modeling \(A\), only the type of beam element changes. In this case it’s POU_D_EM elements.

4.2. Tested sizes and results

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

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