határoutput

Határoutput is a term used in Hungarian technical writing to describe data that is produced at the boundary of a system, domain, or data sequence. It is not a standardized term in international nomenclature, and its precise meaning can vary by field and context.

Origin and meaning: The word combines határ, meaning boundary or limit, with output, a loanword from English. In practice, határoutput refers to the data that resides at or is produced specifically for the edge of a model, signal, or dataset.

Contexts and usage: In numerical simulations, határoutput typically denotes the values stored at boundary nodes or cells after applying boundary conditions such as Dirichlet or Neumann conditions. These boundary values can be used for coupling with adjacent domains, for reporting results, or for interface with other parts of a simulation. In parallel computing, határoutput can refer to data exchanged in halo or ghost regions between processes. In image or signal processing, it may describe the edge results obtained after applying filters or transforms, where padding schemes influence the output at the borders.

Relation to related concepts: Határoutput is related to, but distinct from, boundary data, boundary values, and boundary conditions. It is not universally used outside Hungarian contexts; in many texts, authors may prefer expressions such as boundary output, boundary data, or boundary values.
