RF-Mode Analysis- Electrostatic field

I'm a french student in an engineering school, and for an internship I need to use comsol. I have to study electro-optic's effect, and particularly modes at the exit of an light guide.
In electro-Optic the refractive index can be modified with an Electric field (An Electrostatic field).
I have defined a 2D Structure representing the sectional view of my waveguide. I apply with 2 electrods an electrostatic field on the structure , and I define a electromagnectic field which goes in the waveguide ( it represents the light guided).
But after compilation of the study, my potentiel is not as defined previously by the 2 electrods , and is really weird. (Like noise but with high magnitude), and then my electrostatic field too. ( and I need it to stay as defined)
Do you know why my Electrostatic field/potentiel is changing ? and How I can resolve this problem ?
