BornAgain is an open-source software project to simulate and fit reflectometry and grazing-incidence small-angle scattering (GISAS), using distorted-wave Born approximation (DWBA).

Developed and supported by the Scientific Computing Group at MLZ, Garching.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 654000 (SINE2020).

The extension of BornAgain to reflectometry was funded under schedule NIK4#11 as part of the data analysis and modeling work package to the contribution agreement between the European Spallation Source ERIC and Forschungszentrum Jülich.
