can the electric field to continually adapt to the deformed mesh?

Hi,

I have created a FSI model with moving mesh, which is using an ElectroOsmotic Flow velocity to deform a solid membrane. The EOF is couple with the electrostatic by E field. And the FSI type is using the fully couple. My issue is, the E field calculated from the electrostatic model is not considering the deformed mesh, I realize that because I can´t see a very strong of variation of the E field due to the deformed domain. I use the fully coupled pardiso solver, version of COMSOL 5.4.

Please see the attached images. "electric_E" is E field calculated only with a deformed mesh. "coupling_E" is when the E field is calculated, coupling the three physic.

What am I missing in my model for the electric field to continually adapt to the deformed mesh?

Thanks,

Daming
