transport of charged species under the electronic field

Please login with a confirmed email address before reporting spam

Dear all:
I have been modeling this topic for several weeks and yet I cannot get an answer.Can someone help me check my model to see where the problem is?Thank you in advance.
What I defined in the model is that I defined a rectangular shaped material in the order of micrometer.Next I added the electrostatics module and the transport of diluted species in the module.Then,I defined the relative permittivity to be 3.8 and I add electrical potential on the right and left side of the material in electrostatics module.I also defined to species to show up in the model,and their diffusion coefficients,migration coefficients and charge number.I want to see how does the species transport inside the material under the effect of diffusion and migration.but when I run the study,the result shows it cannot find the consistent initial value.I don't understand.
