* Capacitance matrix of glass plate capacitor 0.28x0.28x0.006 m
*
C passive.txt 1.0 0.00 0.00 0.000 0x99000055
*
C active.txt 1.0 0.07 0.07 0.10 0x100000ff
*
C active.txt 1.0 0.07 0.07 0.006 0x100000ff
*
C passive.txt 1.0 0.00 0.00 0.106 0x99000055
D glplate.txt 1.0 1.0 0.0 0.0 0.00 0.01 0.01 0.001
D glplate.txt 1.0 1.0 0.0 0.0 0.10 0.01 0.01 0.101

Dear Enrico,
Could you please help me? I really need to know how to add the values of the permittivities in my algorithm.

Hi Zoubayr,
FastCap/FasterCap do not support D elements with different permittivities on the two sides, i.e. infinitely thin conductors in contact with different materials.
FastCap/FasterCap always assume that the conductors are 3D. So you must use a conductor with thickness, that is a box, however thin, composed by panels each of which can be in contact with a different material (e.g. top different from bottom).
You can find some examples in the 'Samples' directory when you install the FastFieldSolvers bundle on Windows. For the location of the directory, if not found, you can see the embedded online help of FasterCap.
Best Regards
Enrico
