Setting the Material Threshold

The material thresholds tell the Maxwell 2D and Maxwell 3D solvers how to deal with conductors and insulators. Materials with conductivities above the Perfect Conductor threshold are treated as having infinite conductivity and surface current only. Materials with conductivity values below the Insulator/Conductor threshold are treated as insulators with no conductivity and no current carrying capability. Materials that fall between the two thresholds are treated as normal conductors that can carry current throughout the volume of the material.

  1. Click Maxwell > Design Settings. The Design Settings dialog box appears.

    2. The material thresholds are set in the Material Thresholds tab.

  2. Type a value in the Perfect Conductor text box.
  3. Type a value in the Insulator/Conductor text box.
  4. Click OK.
