5. Summary of results

The differences between the results of Code_Aster and SAMCEF calculations with consistent masses are less than 0.2%.

The differences between Code_Aster calculation results with diagonal masses and SAMCEF with coherent masses remain less than 1%.

These results are in accordance with what could be expected, and reliably validate the natural frequency calculations in Code_Aster by CALC_MODES and the CALC_MATR_ELEM operator in coherent masses as well as in diagonal masses.
