AuxVariable

Represents standard field variables, e.g. Lagrange, Hermite, or non-constant Monomials

Auxiliary variables are used to compute or store intermediate quantities that are not the main variables, the ones being solved for, of the equation system.

A detailed description of the MOOSE variable system is given in the base class documentation.
