AIB 2011-16: Toward Adjoint OpenFOAM

The following technical report is available from http://aib.informatik.rwth-aachen.de: Toward Adjoint OpenFOAM Niloofar Safiran, Uwe Naumann AIB 2011-16 OpenFOAM is a package which simplifies the implementation of physical models by mimicking the form of partial differential equations in software. Use of OpenFOAM is rapidly expanding in the research community and among industrial users, covering a wide range of continuum models. AD provides accurate derivative values and better runtime performance of the adjoint model compared with finite differences. This paper presents a transformation of the OpenFOAM code that can be used for calculating derivatives with adjoint mode of AD. An example based on ODE is considered here.
