OpenFOAM® 1.7.x (and previous versions) provides a wide range of LES SGS models, however the implementation of the models based on the dynamic procedure, originally proposed by Germano, is not suitable for flows in arbitrary geometries, since the coefficient, determined dynamically, is averaged over the whole computational domain. I implemented a modified version of the dynamic model, based on the work of Lilly (1992), and I made it available through my git repository for those interested. Please, refer to the README file for instructions.
