Calculates a single frequency ODS due to multiple sinusoidal excitation forces.
The Sinusoidal ODS can be saved in a Shape Table or displayed in animation in a connected Structure window.
The ODS is calculated by multiplying FRFs by the Fourier spectra of excitation forces at a single frequency.
Forces can be applied at any Reference DOF of the FRFs
Each force is defined by its magnitude & phase, and the Reference DOF at which it is applied. to the structure
The DOFs of the Sinusoidal ODS are determined from the Roving DOFs of the FRFs.
When this command is executed, the following dialog box is opened.
Sinusoidal ODS From a Data Block.
Press the Animate Shape button to display the Sinusoidal ODS in animation on the structure model in a connected Structure window,
The M# Links in the connected Structure must be compatible with the M#s of the Sinusoidal ODS in order to display it in animation.
To insure that the Sinusoidal ODS will animate correctly,
Press Save Shape to save the ODS into a Shape Table.
Execute Animate | Create M# Links from the Shape Table to create new Animation Equations in the connected Structure window.
