+==== Natural frequencies ====
+First three natural frequencies (with clamped root) for the mesh computed with OpenMCAD[(cite:Kojtych_2022_gene_aubes)]:
+^ Mode  ^ Type  ^ Natural angular frequency (rad/sec)  ^ Natural frequency (Hz)  ^
+| 1     | 1F    | 1018,5                       | 162,1                  |
+| 2     | 1T    | 3542,5                      | 563,8                  |
+| 3     | 2F    | 6094,7                      | 970,0                  |
+===== Initial blade =====
+The **initial blade** is defined with in-house LAVA parameters[(cite:Kojtych_2022_Methodology>Kojtych S. //et al//. “Methodology for the Redesign of Compressor Blades Undergoing Nonlinear Structural Interactions: Application to Blade-Tip /Casing Contacts" 2022. Journal of Engineering for Gas Turbines and Power, Vol.145, No.5. {{ https://hal.archives-ouvertes.fr/hal-03795257|pdf}})]obtained from CAD model of the reference vane. The initial dawn is conventionally used as a starting point in optimization procedures; its geometry is similar to that of the reference blade.
