Webcommented Apr 3, 2024 by miguelito FEniCS Novice. Hi. Here is the idea: Chemical and the electrical fields should be solved simultaneously for 2 unknowns: 1- C_alpha. 2- Electric potential. And finally the values of C_alpha should be used in the last equation (equation of motion) to find the displacement (u). I hope I explained it well!
