Description
    Solver for unsteady 3D turbulent flow of incompressible fluid governed by
    quasi-hydrodynamic dynamic (QHD) equations with support for deforming
    meshes.

    QHD system of equations has been developed by scientific group from
    Keldysh Institute of Applied Mathematics,
    see http://elizarova.imamod.ru/selection-of-papers.html

    Developed by UniCFD group (www.unicfd.ru) of ISP RAS (www.ispras.ru).
