From OpenFOAMWiki

We are the small scientific laboratory which does the development of software for numerical simulation using open-source technologies: OpenFOAM, AMReX, Code_Aster, ParaView, etc. For example: libAcoustics library, solver with hybrid Godunov-SIMPLE approximation, QGD/QHD regularized solvers. Also, we maintain training materials for OpenFOAM: . The mission of our laboratory is to spread open-source software in Russian industry and academical research and universities.
