Hello to everyone. I encountered with a problem during using an nonlinear material, where a relative permittivity depends on electric field strength in a certain material. During the simulation I got an error "Attempt to evaluate negative power of zero. Function: ^...". The model is attached (SCT_v3_linear_.mph, Model 3). This is the same model as the model considered here (quickfield.com/advanced/telec3.htm). Could some one possibly tell me how I can fix the problem, where I am wrong. This problem I got in electrostatic and in electric currents. Changing of Initial values has no effect.
Thank you very much for any help, idea, advice.
