Описание
Creates a FEM constraint for the electrostatic potential. To be used together with the Electrostatic or Electricforce equation.
Применение
- Either press the FEM ConstraintElectrostaticPotential button or use the menu Model → Electromagnetic Constraints → Constraint electrostatic potential.
- In the 3D view select the object the constraint should be applied to.
- Press the Add button.
Опции
The dialog offers the following settings:
- Potential: The electric potential in V.
- unspecified': To declare the potential as unknown for the solver.
- Vector Field: To enable the input of the components of a potential vector field.
- x: The real/imaginary part of the potential in x-direction in V.
For other coordinate systems than Cartesian 3D, this will be the first coordinate of the system instead of x. - y: The real/imaginary part of the potential in y-direction in V.
For other coordinate systems than Cartesian 3D, this will be the second coordinate of the system instead of y. - z: The real/imaginary part of the potential in z-direction in V.
For other coordinate systems than Cartesian 3D, this will be the third coordinate of the system instead of z. If the coordinate system has no third coordinate, this setting will be ignored. - x, y, z checkboxes: To declare the corresponding potential as unknown for the solver.
- 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.
