Use free grid

HiI am a researcher and I would like to use EFDC, as an open source code, for simulation of an estuary. I want to use Free Grids released in your website. I want to ask you, i can do it? Do not I encounter any problem related to license or copyright?Thanks

AliPlease feel free to use the grids. We would like to request you to provide proper reference to the source in your final reports or journal articles.Thanks
