FunctionGradientNeumannBC
FunctionGradientNeumannBC adds the weak form contribution: where is the unit normal vector at the boundary, is a coefficient (corresponding to thermal conductivity or diffusivity), and is a function of space and time that is specified in the input file through the parameter exact_solution. As the parameter name suggests, the FunctionGradientNeumannBC object can be useful for specifying a Neumann condition when the exact solution to the PDE is known.
Imposes the integrated boundary condition arising from integration by parts of a diffusion/heat conduction operator, and where the exact solution can be specified.
