Description

Creates a FEM boundary condition for the current density. To be used together with the Magnetodynamic and Magnetodynamic 2D equations.

Usage

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

Options

• Current density_*_1: The real/imaginary part of the current density in x-direction in A/m².
  For other coordinate systems than Cartesian 3D, this will be the first coordinate of the system instead of x.
• Current density_*_2: The real/imaginary part of the current density in y-direction in A/m².
  For other coordinate systems than Cartesian 3D, this will be the second coordinate of the system instead of y.
• Current density_*_3: The real/imaginary part of the current density in z-direction in A/m².
  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.
• Current density_*_*_Disabled: Whether the corresponding parameter is disabled (assumed as unknown by the solver).
