Description

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

Usage

  1. Press the FEM ConstraintCurrentDensity button or use the menu Model → Electromagnetic Constraints → Constraint current density.
  2. In the 3D view select the object the constraint should be applied to.
  3. Press the Add button.

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).
