		const FEVariablesBase &	fe_var,
		const std::string &	section
	)

protectedpure virtual

Builds the NeumannBCAbstract object for Neumann boundary conditions.

Subclasses should override this function to build the NeumannBCAbstract object that corresponds to the variables passed in var_names. The FEVariableBase object corresponds to the variable associated with this boundary condition, e.g. Velocity. The section arguments corresponds to the section to parse for the flux in the input file, e.g. input(section+"/"+flux). Note that for Variables with more than one component, the flux input should be a vector the size of the var_names object, even if one of the components is zero.

		const std::string &	section,
		const std::vector< std::string > &	var_names
	)

protected

Checks that the flux variable has been set.

Check for both the presence of [section/flux] and that the size is the same as var_names. For example, if we are setting a traction vector for Displacement variables, then the input flux vector (traction) should have the name number of components as var_names.

libMesh::UniquePtr< NeumannBCContainer > GRINS::NeumannBCFactoryAbstract::create ( )

virtual

Creates NeumannBCContainer for this Factory object.

This method will handle the creation and population of all aspects of the NeumannBCContainer except the function object that is used to evaluate the flux, the NeumannBCAbstract object. The construction of NeumannBCAbstract subclasses is deferred to subclasses of this factory and should be implemented in the build_neumann_func method.

Note that an empty libMesh::UniquePtr<NeumannBCContainer> may be returned from create() if the parsed boundary condition type is a homogeneous one. This is allowed since we force the user to specify boundary conditions for every Variable, for every boundary in the hopes of reducing input file errors at runtime.

Implements GRINS::FactoryAbstract< NeumannBCContainer >.

bool GRINS::NeumannBCFactoryAbstract::_is_homogeneous

protected

Track if this is a homogeneous Neumann boundary condition.

If so, then we literally do nothing: don't create a NeumannBCAbstract object, don't create a NeumannBCContainer, etc. Default is false, so subclasses have to opt-in appropriately.
