How can I vary the current density in a conductor face region in magneto static application?


In order to vary the current density in a conductor in magneto static application, you have to follow the next steps: 

  1. Create two IO parameters:
    I: current in (A)
    SURF: surface in (mm²) on which the current circulate (the slot surface for example)
  2. Create a spatial quantity named CURRENT_DENSITY and defined as follow CURRENT_DENSITY =IO(I)/IO(Surf)
  3. Affect the spatial parameter CURRENT_DENSITY to the face region “Region with current density”.
  4. In the solving scenario: you can vary J and SURF, it will vary CURRENT_DENSITY.
