2. Benchmark solution#
2.1. Reference quantity and result#
A reference of type NON_REGRESSION is used to check the prestressed natural modes. We calculate the 5 smallest natural modes. The results are compared by the « direct » calculation and by the calculation on a sector with cyclical boundary conditions.
2.2. Reference quantity#
FREQ: frequency
2.3. Reference quantity and result#
The reference results presented below correspond to the results obtained with 3D modeling:
