**v2.03.102** SDLS102 - Free vibrations of a compression blade
====================================================================

**Summary:**

This test makes it possible to validate the calculation of the natural frequencies of a compression vane using the command CALC_MODES.

The models correspond to the use of elements COQUE_3D MEC3QU9H (modeling A), MEC3TR7H (modeling B) and COQUE_SOLIDE (modeling C).

The reference solutions are experimental results. The difference between the numerical results and the experimental values does not exceed :math:`\text{4,5\%}` for the three models.
