Using the Fields Calculator

The Fields calculator enables you to perform computations using basic field quantities. The calculator will compute derived quantities from the general electric field solution; write field quantities to files, locate maximum and minimum field values, and perform other operations on the field solution.

The calculator does not perform the computations until a value is needed or is forced for a result. This makes it more efficient, saving computing resources and time; you can do all the calculations without regard to data storage of all the calculated points of the field. It is generally easier to do all the calculations first, then plot the results.

A online help Fields Calculator Cookbook provides examples of the following:

• Calculating Numerical Quantities

• Calculating Quantities for 2D (Line) Plot Outputs

• Calculating Quantities for 3D (Surface or Vector) Plot Outputs

• Calculating Quantities for 3D (Volume) Plot Outputs

• Calculating Quantities for Animated Outputs

• Creating User Defined Named Expressions Library
