Hi Peter,

Yes I will correct the material and geometry because as you said they are not realistic but does the coating layer have significant effect on the results?

And just a question from my last post, if you look at the plot of the force reaction for six parts( which are human teeth), you will see some are positive and the rest are negative which I expect only tensile ones not compression because the connection between teeth and tray are not bonded, they are frictionless. What would be the reason?
