GenericFunctorGradientMaterial

FunctorMaterial object for declaring properties that are populated by evaluation of gradients of Functors (a constant, variable, function or functor material property) objects.

Overview

This object creates vector functor material properties that are gradients of other functors.

commentnote

All AD-types of the properties defined in this material must match. Variables are automatically considered as AD functors, even auxiliary variables. The AD version of this material is ADGenericFunctorGradientMaterial. Its inputs are a vector of AD functors and it creates AD vector functor material properties.

Example Input File Syntax

In this example, ADGenericFunctorGradientMaterial is used to compute the gradient of the variable u, which is then multiplied by a diffusion coefficient to obtain the diffusive flux. This flux is computed at the element centroids, not one the element faces.
