3. Reference solution: B modeling

3.1. Calculation method used for the reference solution

The calculation carried out here is identical to that of modeling A, on a modal basis. This calculation makes it possible to validate the orders

• PROJ_BASE option RESU_GENE: projection of a temporal evolution (dyna_trans) on a mode basis,

• DYNA_VIBRA, on a temporal basis (TYPE_CALCUL =” TRAN “) and on a modal basis (BASE_CALCUL =” GENE”) with an excitement defined by option EXCIT_RESU.

3.2. Benchmark results

The results tested in modeling B are the same as for modeling A. The reference values are different, because the values of the bands and the calculation steps are different. The sampling frequency chosen for the time calculations is 1000 Hz.
