Ansys Workbench

This is more of help on using ANSYS workbench 12.1. I have created two ANSYS project files representing my problem of study. The problem is a cylindrical shaped part consisting of three different bodies. One of these bodies is made up of Piezo material. The problem is symmetric for now. Therefore I modeled only quarter the geometry. I tried to input the piezo command lines (piezo dielect and stress). However, it does not work (2D layer workbench project) or it works but not properly (3d-quart workbench project). Tasks: 1) How to input piezo material properties properly? How to align them with the correct directions? How to change polarization if desired? (I have placed some commands under the piezo body as to change element type) 2) How to use the model as an actuator? (Apply electric-volt and receive mechanical-stress/strain) What are the exact additional command lines (I have placed some command lines)? 3)How to use the model as a sensor? (Apply mechanical-stress/strain and receive electric-volt) What are the exact additional command lines? 4) How measure radial stress, shear stress on curved surfaces (r-theta shear stresses)
