Surface charge density of a floating potential electrode

Hi,
I try to analyze the charge distribution of a floating potential electrode. so I simulate the surface charge density of a floating potential electrode in eletric field. Please see the attachment. I choose boundary condition of this eletrode is floating potential (charge is 0 C), solver can also work, but there is error if I plot the surface charge density.
"can not evaluate expression:
fail to evaluate variable
variable: mod1.es.nD
fail to evaluate expression:
expression:mod1.es.nD"
I don't know what is wrong about the boundary condition? Or another words, how can I set up the floating potential electrodes in E-field?
thank you very much!
