Why does the error occur in Q3D?

    • Myung Chul Hyun

      I have just simulated Q3D to calculate capacitance in simple two plates.

      But there is difference simulation and hand calculation.

      Capacitance (hand calculation) = e0erA/d = 8.854e-12*10mm*10mm/0.1mm

      = 8.854pF

      simulation result is 9.231pF

      The agreement between both values is within 4% so it is acceptable
