Modal FRF - Define Response

Calculate and export responses.

Nodes

Select the nodes for extracting the response. Select the type of response (displacement, acceleration, or velocity) for the selected nodes.

Import/export the excitation nodes from/to a CSV file. You can create an LCS using axis-plane and/or Euler angles, and then request the response in LCS or the normal direction.

Frequency

Enter the Min, Max, and increment size for the frequency range of analysis.

Calculate and Export Responses

Calculates the frequency response for the sensitivity subcases or actual excitations and exports the data into a PCH file format. The exported PCH file gets loaded into the vehicle response tab.
