(Integral) Command ∫

Takes the integral of a scalar quantity over a volume, surface, or line. The top register must contain a geometry, and the second register must contain the scalar quantity to be integrated.

To perform an integration:

  1. Load a quantity into the top register of the calculator, and perform any required operations on it.
  2. Use one of the Geometry commands to load the line, surface, or volume over which the quantity is to be integrated.
  3. Note: If you computed the tangent or normal of the quantity to be integrated, you do not have to load a geometry onto the calculator stack. Maxwell integrates the tangential or normal component of the quantity over the line on which you computed its tangent, or the surface on which you computed its normal.
  4. Click the Integral command to integrate the scalar quantity over the geometry. In 2D designs, you must further select either XY or RZ.

To find the numerical results of an integration, use the Eval command.

Note: In Maxwell 2D, the Fields Calculator accounts for the difference between XY and RZ models when handling data and results. The integral command will perform an XY integral on the model assuming a 1 meter depth, while for an RZ model it will perform an integral on the 360 degree equivalent volume.
