Frequency Response simulation for Ultrasonic Horn

The main aim is for me to tune the Horn to match the frequency of the transducer which is 40 kHz, I am trying to simulate this in SW.

When I first ran the simulation, SW produced five resonant frequencies ranging from 1000-8000Hz, however I found an option to increase the modal results. Why does SW produce five result to begin with, is there any particular reason.

Secondly, when I altered the modes to around 20 the frequencies ranged from 1000- 20000Hz

How can I be able to produce the response I am looking for. I.e. a linear vibration motion with a frequency around 40 kHz, also where would one recommend the fixings, would this be the connection on the shafts of the connecting plate as I only wish the horn to vibrate.?
