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

The quantities tested and analyzed are the first values of buckling loads in both directions.


.. csv-table::

    "", "Theoretical Values", "Tolerance (%)"
    "1st Mode/:math:`{I}_{z}` ", "5757.3N", "0.2"
    "1st Mode/:math:`{I}_{y}` ", "24180.5 N", "0.2"
    "2nd Mode/:math:`{I}_{z}` ", "23029.1 N", "0.2"
    "3rd Mode/:math:`{I}_{z}` ", "51815.4 N", "0.2"
    "2nd Mode/:math:`{I}_{y}` ", "96722.1 N", "0.2"
    "4th Mode/:math:`{I}_{z}` ", "92116.3 N", "0.7"


The calculation times 1 and 2 give the same results. The calculation of the prestress vector after STAT_NON_LINE is therefore carried out correctly.
