FEM ConstraintElectrostaticPotential/it

Descrizione

Utilizzo

1. Press the Electrostatic potential boundary condition button or use the menu Model → Electromagnetic boundary conditions → Electrostatic potential boundary condition.
2. Press the Add button.
3. In the 3D view select the object the boundary condition should be applied to.

Options

The dialog offers the following settings:

• Boundary Condition - introduced in 1.1: To choose between Dirichlet (prescribed potential) and Neumann (prescribed electric flux/surface charge density) boundary condition type.
• Potential: The electric potential in V.
• Electromagnetic Potential: 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.
• Electric Infinity: Option to make a spherical approximation that the volume above the face extends to infinity.
• Potential Constant: Option to set a constant potential.
• Surface Charge Density - introduced in 1.1: The surface charge density (electric flux) in C/m^2.
• Capacitance Body: Counter of the body (or face) with a capacitance.
