Each spatiogram is representative of a spatial distribution of the Electromagnetic forces. The sum of the participation of each spatiogram lead to the global vibration response. Determining the spatiogram responsible of the vibration harmonic that should be decreased is one of the major objectives of the EVHV module. | Each spatiogram is representative of a spatial distribution of the Electromagnetic forces.
