Electric Potential BC in ABAQUS

[JimmyJazz13]

Hi, I'm using piezoelectric material in ABAQUS, and I would like to have some pieces activated with 0 dephasing and some with 180 degrees (so they go in opposite direction at any given time). I know how to impose the initial condition and to apply the voltage magnitude but not how to dephase some...


Thanks a lot!!!

Also, I use 400 V as Magnitude BC condition, and I tried -400 V and obtained different results from when I use 400 V... what's the signification?
