  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
