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
