Abstract

AbstractThe Unified Form Language – UFL [Alnæs and Logg, 2009] – is a domain specific language for the declaration of finite element discretizations of variational forms and functionals. More precisely, the language defines a flexible user interface for defining finite element spaces and expressions for weak forms in a notation close to mathematical notation.KeywordsDirected Acyclic GraphElement SpaceComputational GraphForm ArgumentAutomatic DifferentiationThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
