    Connecting a resistor to piezoelectric elements (ANSYS Mechanical APDL)

    Hi, I'm modelling a vibrating piezoelectric energy harvester in ANSYS, consisting of an upper face (with coupled voltage degrees of freedom) and a lower grounded face (with an assigned voltage boundary condition of 0 volts). I need to connect a resistor across the upper and lower faces but...

    Disappearing menu items / degree of freedom coupling issues - ANSYS Mechanical APDL 18.2

    Hi, I'm using ANSYS Mechanical APDL (either 18.1 or 18.2) to model a piezoelectric energy harvester. For some reason, under the preprocessor menu the 'Coupling/Ceqn' tab has disappeared and I have no idea how to get it back. When I was previously able to access the 'Coupling/Ceqn' tab to...

    How to couple piezoelectric elements in ABAQUS?

    I've looked through the sections in the User Manual and Example Problems Guide on piezoelectric analysis but there isn't a walkthrough for either of the example problems. Only an input file is provided. I haven't learnt the keyboard commands for Abaqus so unfortunately it doesn't make any sense.

    How to couple piezoelectric elements in ABAQUS?

    Hi, I'm using ABAQUS to model some vibrating piezoelectric energy harvesters. I'm aware that I need to couple the voltage degree of freedom of each piezoelectric element and assign them all the same value but I have no idea how to do this. I also need to connect a simple resistive load to the...
