i have design simple rectangular cantilever beam of dimension 3mmX10micrometerX25micrometer whose sub domain is PZT 5a and boundary condition are one end is fixed and other is having pressure in
Fy =-1000*sin(2*pi*96*t) / (10micrometer*25micrometer) N/m^2 and bottom surface is ground and top surface is zero charge symmetry then i am taking voltage from beam tip point which is sinewave now my question is that can i take same voltage from metal electrodes which have pzt layer in between them and giving same boundary condition.
i have tried structure with two metal electrode but as metal are good conductor they should have constant voltage throughout their length but comsol shows variation in voltage along length.
and other question is that can connect load resistor across electrode through spice editor if yes then how to calculate power from that.
