Hi all,

Does anyone know how to measure vortex shedding frequency in fluent? I am modelling flow pass through a bluff body e.g. cylinder.

Thanks.

Sham.

Perform an FFT on an appropriate variable-time trace in an appropriate position.

Does that mean we apply FFT on lift coefficient? What do you mean at an appropriate time trace and position?
