MooseVariableFE

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

A MooseVariableFE is a derived class of a MooseVariableField. It is a finite element field variable. Depending on the finite element family (chosen with "family" parameter) or the "components" parameter, it can be a regular, vector or array variable.

A MooseVariableFE can be a nonlinear variable, in which case it should be created in the [Variables] block, or an auxiliary variable, in which case it should be created in the [AuxVariables] block.

A MooseVariableFE is a Functor. As such it may be specified in the functor parameter of numerous polyvalent objects.
