*COMPLEX FREQUENCY

Keyword type: step

This procedure card is used to determine frequencies taking into account
Coriolis forces (cf. Section 6.9.3). It must be
preceded by a *FREQUENCY step in which the eigenvalues
and eigenmodes are calculated without Coriolis (do not forget to use the
option STORAGE=YES in the frequency step, ensuring that the eigenmodes and
eigenvalues are stored in a .eig file). The frequency step does not have to be
in the same input deck. There is one required parameter CORIOLIS.

Finally, the number of
eigenfrequencies requested should not exceed the corresponding number in the
frequency step.

First line:

- *COMPLEX FREQUENCY
- use the required parameter CORIOLIS

Second line:
- Number of eigenfrequencies desired.

Example:
*COMPLEX FREQUENCY,CORIOLIS
10

requests the calculation of the 10 lowest eigenfrequencies and corresponding eigenmodes.
