Please Help! Electrical simulation problem

Please login with a confirmed email address before reporting spam

Hi everyone,
I have a problem with an electrical model.
My model is a nerve (a simple cylinder made of three different materials) with two electrodes situated on the surface of the nerve. One of these is the ground and the other one is the stimulating electrode. The simulation works and there aren't errors, but the distribution of the electric potential is not as I would have expected. The distribution is symmetrical but I would expect a higher potential towards the stimulating electrode, without a so big influence of the ground electrode. This is the first time I use comsol for electrical models, so I don't know what's the problem. I think that there could be problems with the definition of the physics (for example the boundaries conditions) or with the characteristics of the materials.
Thanks in advance to anyone who can help me.
