Modal frequency response analysis

User: "Altair Forum User"

Hi sir,

I performed a modal analysis (with constraints) and a modal frequency response analysis on a motor. Modal analysis results shows the natural frequency starting from 322 Hz (1st NF) . while the Freq. response analysis results shows the Natural frequency starting from 30,712 Hz (1st NF). According to my knowledge both the analysis should produce same Natural frequencies as all the conditions are same. Both the '.out' files are attached below. Please help me figure out what has gone wrong.

Thank you
