harmonic initial state
Starts every mode on its harmonic response to a point force, instead of at rest
locationrequired
vector (3 floats)·required
Point the force acts at; the force there is written to the modal history
forcerequired
vector (3 floats)·required
Force vector (N); its magnitude sets each mode's initial displacement and velocity
frequencyrequired
float·required
Frequency of the harmonic force (Hz)
