FunctorAux
Evaluates a functor (variable, function or functor material property) on the current element, quadrature point, or node.
Overview
This object populates an elemental auxiliary variable by evaluating a functor with a cell-center/elemental or quadrature-point based argument. This functor may be a material property, a function or another variable. A cell-center/elemental argument should be used when a cell-averaged quantity (like for finite volume computations) is desired. Cell-center/elemental vs. quadrature-point based evaluations are controlled by the use_qp_arg boolean parameter. By default the parameter is false.
commentnote
The version of this auxiliary kernel for automatic differentiation (AD) functors (in particular AD material properties) is FunctorAux.
Example input syntax
In this example, we use FunctorAux to convert some material properties functors, defined by the fluid properties material, to auxiliary variables, to examine them in an Exodus output.
