Coupling electrostatic with General form :Error

Please login with a confirmed email address before reporting spam

Hello everyone! I am working on 2D simulation of transistor. I am using electrostatic to solve Poisson equation at the equilibrium , then I added another electrostatic interface to solve it in non-equilibrium. after that I added General form to solve continuity equation for electrons. when I run the simulation separately, I got good results, but when I solve for both electrostatic and General form, I got Error. there is 9812 equations undefined for variable V2. there is 9812 equations undefined for variable fain. Could you please help me to figure out the error. thank you
