Boundary Loads Piezoelectric Modeling

Please login with a confirmed email address before reporting spam

Hello,

I have a question. I am modeling a piezoelectric and I want to apply a load to it to generate charge, current or voltage. I am using the boundary load condition and would like to use the following equation for applying the load Fz=A*sin(w*t)=A*sin(2*pi*f*t), I want to run the study which will input the frequencies and the time in the boundary load. Right now I am doing a time dependent study only so my equation looks like Fz= A*sin(2*pi*100E3*t) in which I believe the ( t ) in the equation comes from my study, is that correct? if it is how do I modify my study and boundary load so that it also inputs the a frequency range in to my load equation? lets say I want to study 100kHz:200kHz range with the t range from (0,0.1,1)?

Thanks.

Juan

choose study as "frequency domain" where you can apply input frequency .. you have the option of specifying the range..

no need to mention frequency and time in your boundary condition.. just apply the numerical value in the boundary condition...
