Hello everyone, I'm trying to simulate the piezoelectric energy harvesting with cantilver beam and when check the multi physics coupling says all the domains are not applicable as shown in the attached screen shoot. i have made the material type for the charge conservation as solid and still problematic, and results to have zero voltage generation , since i want to plot the frequency with voltage output. would you please help me on fixing these problem.

Thank you for your help

You must use a Charge Conservation, Piezoelectric node.
