Creates a FEM constraint for the electrostatic potential. To be used together with the Electrostatic or Electricforce equation.


  1. In the 3D view select the object the constraint should be applied to.
  2. Press the Add button.


The dialog offers the following settings:

  • Potential: The electric potential in V.
  • Potential Constant: Option to set a constant potential.
  • Farfield / Electric infinity: Option to make spherical approximation that the volume above the face extends to infinity.
  • Calculate Electric Force: Option to trigger the calculation of the electric for using the Electricforce equation.
  • Capacity Body: : Counter of the body (or face) with a capacitance.
