Hi, I am doing Maxwell Electrostatics Simulation.

So how do I evaluate Capacitance at a particular location/node/point?

If I use the formula, it is C = Q/V. But how should I use it in calculator?

Thanks!!!

In Electrostatics solver, capacitance is calculated between two conductors by simlating the electric field that arises when a voltage differential is applied.

If you want to use field calculator, you can calculate the total electric charge on an object and divid the voltage value.

• Qty -> D (load D vector into the calculator);
• Geom -> Surface… (select the surface of interest) -> OK
• Normal
• Integrate
• number...->scalar->value: (voltage value)->OK
• /
