Sounds suspiciously like this is fostering a well known misconception.
The Tacoma Narrows Bridge was not driven by an oscillatory wind; it
was an aeolian oscillation driven by a steady wind. I will guess that
the simulator demonstrates a resonance phenomenon. As I've pointed out
more than once, the Tacoma Narrows Bridge collapse is not an instance
of a resonance phenomenon.
