Hi,

I would like to simulate the surface charge accumulation on a polymeric sphere. This sphere is between two electrodes and there is an Electric Field. The final result must be an assessment of the induced polarization.

Since I am a chemist, and I am having some problems to solve this issue.

I am enclosing my model until now. May anyone help me?

Best

I just tried to run your model, but
1) It seems as if a number of material properties are not defined (do you not see the red 'x' in your model builder?
2) When I try to solve the model as you posted it, i get the error that duplicated variable names are present.
Maybe you want to fix this first..?
Do you have a working model, could you upload it?
