DVextract_comp creates a new field object that is a reference to one component of an existing Node_Data. The component can be scalar or vector. Most modules that work on Node_Data work on just one component of Node_Data. DVextract_comp is the base module that they use to acquire this single component.
An integer. Sets which component of the input Node_Data to extract. The default is the first (0th) component.
A reference to a field containing a Mesh and Node_Data.
A reference to a merged object. That object's first member is a reference to the extracted Node_Data component. The object's second member is a reference to the remainder of the input field.
