Modeling POU_D_T:


.. csv-table::

    "Number of nodes", ":math:`49` ", "", "", ""
    "Number of meshes", ":math:`48` ", "That is:", "", ""
    "", "", "SEG2 "," :math:`48`"


     Group of meshes

     :math:`\mathrm{GM1}`: set of SEG2 meshes that make up the beam


Tested sizes and results
------------------------------

 For the first analysis of the modeling, considering the transient dynamic response on a modal basis consisting only of the first 30 natural modes, we obtain a value of :math:`\mathrm{RMS}` as follows:

.. csv-table::

    "Quantity", "Component", "Node", "Calculated value"
    "FORCE_NORMALE "," RMS_T_TOTAL "," :math:`\mathrm{N2}` "," :math:`23.98`"


For the second analysis, considering the static correction for the modal base, we obtain a value of :math:`\mathrm{RMS}` that is slightly different and certainly closer to reality given the improvement of the modal base:


.. csv-table::

    "Quantity", "Component", "Node", "Calculated value"
    "FORCE_NORMALE "," RMS_T_TOTAL "," :math:`\mathrm{N2}` "," :math:`24.538`"
