The Calculator Stack
The calculator is made up of a stack of registers, each of which can hold
- field quantities
- functional or constant scalars and vectors
- geometries – points, lines, surfaces, or volumes — on which a field quantity is to be evaluated.
To perform a computation on the field solution, you must first load a basic field quantity into a register on the stack.
Once a quantity is loaded into a register, it can be
- manipulated using mathematical operations such as curls, gradients, cross products, divergences, and dot products
- integrated over lines, surfaces, or subvolumes of the solution region — either predefined surfaces, volumes, and lists, or lines, surfaces, and volumes that were defined using the Draw commands
- plotted on a point, a line, a surface, or a volume
- exported to a file, allowing you to superimpose saved solutions.
