Yes this is a device used in orthodontic treatment which applies vibrational force on the teeth to stimulate them to increase their cell activities.


I will do that for harmonic first to get some approximate results but I still have few questions that I really appreciate if you can help me:


1. Is it necessary to get Modal results? can I go straight forward to the harmonic analysis?if SO, how many modes will I need?


 


2. When I define the steps and step time I get this error. Honestly I don't understand how these options work? also when the auto time stepping and time integration should be on?


 


 



3. I don't know what is the damping coefficient of my model, can I assume a small number? 


Thank you so much.
