how to get initial stress in "pzd" from "solid mechanics" stress?

Please login with a confirmed email address before reporting spam

I am trying to simulate the propagation of ultrasonic wave in small strip after it has been stressed by a static load. so, I selected two two branches of Structural Mechanics physics: "solid mechanics" and "piezoelectric" and selected one study with two steps: "stationary" and "time dependent" respectively. my question is: how to include the stress of the first physics (of the static load) into the second physics (of the wave) which is represented by "pzd"? knowing that I used the "initial stress and strain" under " linear elastic material" for the second physics "pzd" but it was not useful. any note will be helpful.
Best Regards

hi, have you solved this problem? i am doing the same silulation like you did. could you please share you ideas with me? Thanks a lot.
