Specifies the starting frequency for the analysis in Hertz (Hz). This is the frequency at which the harmonic forces or displacements are applied.

Harmonic displacements and forces have the form:

A*cosine(wt - f)

where A is the amplitude of the force or displacement, f is the phase angle, and w is the frequency of the loading.

Real and imaginary solutions are developed for each frequency in the defined range, from which any phased solution can be calculated. There must be a starting frequency for a frequency range to be valid.
