ECT sensitivity distribution maps

Hi,
I am using Comsol ver 3.5a Electrostatics module to design my 12 electrode electrical capacitance sensor in 2D. Now i would like to generate a sensitivity map for this ECT sensor but before that would like to transform my 2D model to 3D. So my first question is that how can i transform my 2D model to 3D?
Then after that, how 3D sensitivity distribution (map) could be obtained using COMSOL?
Sensitivity distribution is essentially a map of the sensor response to a short test probe of high permittivity material in a low permittivity background as it located at different x, y and z positions inside the sensor. In principle, the sensitivity distributions can be obtained by physical measurement or by FE analysis. The 3D sensitivity distribution of electrode pair ij,Sij(k) (the subscript i and subscript j indicate that the measurement electrode i and j are the excitation and the
detection electrodes.
Please help me.
Thanks.

Hi
be aware you need quite som eRAM and time to solve when yuo go from 2D to 3D ;)
Have you tried to extrude or revolve your 2D (respectively 2D-axi) geometry (I belive to remember that existing already in 3.5, common now in V4)

Good luck

Hi,
Yes, I have tried to extrude 2D model to 3D and it does but i dont know what distance value i should choose in Extrude. As I was using 2e-6 but it only shows the top view in 3D, what value i need to key in to observe the whole sensor ?
Thanks for your co-operation.

And also I would like to know that how could I obtain Sensitivity distribution maps for 12 electrode-electrical capacitance tomography sensor that is filled with air,water and oil.
Can COMSOL be used to obtain the sensitivity maps for ECT in 3D ?
