Calculated physical quantities in Electrostatics

Help contents

For electrostatic problems the QuickField postprocessor calculates the following set of local and integral physical quantities.

Local quantities:

• Scalar electric potential U;
• Vector of electric field intensity E = –gradU

  Planar case: \[ E_x = -\frac{\partial U}{\partial x}, \quad E_y = -\frac{\partial U}{\partial y} \]

  Axisymmetric case: \[ E_z = -\frac{\partial U}{\partial z}, \quad E_r = -\frac{\partial U}{\partial r} \]

• Vector of electric induction D = εE, where ε is electric permittivity tensor.

Integral quantities:

See section Integral quantities in Electrostatics.
