Time-mesh in the transition Piezoelectricity acoustics model

Please login with a confirmed email address before reporting spam

Hi,

I'm using comsol V4.2.

In the transition Piezoelectricity acoustics model.
Water:c=1500m/s

I'm using piecewise function : sinewave 1.08MHz,Duty cycle=30%,Burst cycle=10
How can I set time step for model in the time depend?
I know that a wavelength needed to be represented by at least five meshs.
So,I want to know how to set time step in the time depend model to get complete imput signal.

thanks
