Frequency response entities are designed to be used in frequency response analysis. Frequency response analysis can analyze a system response to sinusoidal excitation in the frequency domain. Frequency response analysis is efficient in NVH studies because of fast solving speed by using linearized system and frequency domain analysis.

Additional items such as actuator, input channel and output channel are required to perform frequency response analysis. You can apply input force on the system in the frequency domain using input channel and actuator, and measure system response in the frequency response using the output channel. This section explains how to formulate, create and modify Frequency Response entities.
