Simple 2D model

Please login with a confirmed email address before reporting spam

Hi everyone!

I am new around here and I have to solve this problem:
I have to model human skin with two electrodes on top. Skin has 4 square shaped layers, different permitivity and conductivity. Copper electrodes are cylindrical with AC voltage, 0.5*sin(2*pi*f*t[1/s]). Somehow I will need capacitance and resistivity of skin, probably from voltage drop.

1) Firstly I have problem with application modes ... which one to choose? Is it AC/DC module with quasi-statics/electric OK?

2) Than, in 2D, I create 5 geometries (4 layers and two electrodes), extrude, revolve them to built 3D model. How do I join those elements, with create pairs function?

3) Must there be air all aroud the model?

Please, need some help. Thank you!
