Hi, my model is given as follows:
the bottom trace:
Q 1 0.00000 0.00000 0.00000 0.00500 0.00000 0.00000 0.00500 0.00500 0.00000 0.00000 0.00500 0.00000
Q 1 0.00500 0.00225 0.00000 0.04500 0.00225 0.00000 0.04500 0.00725 0.00000 0.00500 0.00725 0.00000
Q 1 0.04500 0.00000 0.00000 0.05000 0.00000 0.00000 0.05000 0.00500 0.00000 0.04500 0.05000 0.00000
the upper trace consists of two separated pieces:
Q 1 0.00000 0.00100 0.00000 0.00500 0.00100 0.00000 0.00500 0.00400 0.00000 0.00000 0.00400 0.00000
Q 1 0.00500 0.00000 0.00000 0.01000 0.00000 0.00000 0.01000 0.00500 0.00000 0.00500 0.00500 0.00000
Q 1 0.04500 0.00000 0.00000 0.05000 0.00000 0.00000 0.05000 0.00500 0.00000 0.04500 0.00500 0.00000
Q 1 0.05000 0.00100 0.00000 0.05500 0.00100 0.00000 0.05500 0.00400 0.00000 0.05000 0.00400 0.00000
Both the square parts of the upper trace is exactly on top of those of the bottom trace(like parallel plate). I am trying to figure out the the plate capacitance with the parasitic capacitance with voltage applied on the left upper trace and ground on the right upper trace. How can I do that? |

Please check the white paper "The Maxwell Capacitance Matrix" under the 'literature' section.
Best Regards,
Enrico

I think I have got the correct structure now and I obtain the capacitance matrix:
CAPACITANCE MATRIX, femtofarads
1 2 3
1%GROUP1 1 950.4 -264.1 -264.1
1%GROUP2 2 -264.1 405.6 -3.258
2%GROUP2 3 -264.1 -3.258 405.6
How do I obtain those capacitances from it?

Sorry the model should be:
The bottom trace:
Q 1 0.00000 0.00000 0.00000 0.00500 0.00000 0.00000 0.00500 0.00500 0.00000 0.00000 0.00500 0.00000
Q 1 0.00500 0.00225 0.00000 0.04500 0.00225 0.00000 0.04500 0.00275 0.00000 0.00500 0.00275 0.00000
Q 1 0.04500 0.00000 0.00000 0.05000 0.00000 0.00000 0.05000 0.00500 0.00000 0.04500 0.00500 0.00000
