Good morning, in my research work I need to create models of Piezoelectric multiphysics problems. However, as far as I know, the program does not have electrical circuit finite element to make the piezoelectric parts of the structure interact with an external electrical circuit. I am kindly asking you how can I get around this problem? I need to implement a new element with a subroutine? What strategies can I adopt to simulate an electrical resistance that interacts with my piezoelectric structure?
