I am working in energy harvester using PZT. I modeled my beam with PZT using ANSYS Workbench, and assigned the voltage coupling and ground voltage using Ansys workbench, Piezo&MEMS ACT. I need to calculate the variations in voltage or power for different resistance values so I have to add a resistor between the surface of the PZT. I used the ANSYS APDL command to define the resistance value, but for me it is not varying the voltage that is I got error. Can anyone help me in this regards, also, please suggest me, is there any direct way to define a resistor in ANSYS workbench using Piezo&MEMS act. Here with I attached the file for the reference.
