# Frequency List

## Description

Opens a window with the list of frequencies obtained from a modal or modal resantires computation.
In the case of a modal resantires computation, the listed results include the resonance, antiresonance and coupling coefficient for each mode.
There is no list for a static, harmonic, or transient case.

## Illustration

## Remarks

- The frequency list is available as a .FREQ.CSV file in the working directory (ATILA | Open Shell). - In the case of a modal resantires computation, resonance and antiresonance frequencies shown on the same line may not correspond to the same mode (modes can be crossed). Visual inspection of the mode is necessary to associated frequencies correctly. As a consequence, the coupling coefficient shown may be wrong.
- The coupling coefficient is computed as sqrt(1-(fr/fa)2) where fr and fa are the resonance and antiresonance frequencies, respectively.
