QGDsolver is OpenFOAM framework for simulation of fluid flows using regularized equations approach. It contains library for approximation of partial derivatives at face centers of unstructured grids and a set of OpenFOAM solvers:
  • QGDFoam - solver for compressible viscous perfect gas flows in a wide Mach number range - from 0 to infinity
  • QHDFoam - solver for incompressible viscous fluid flows with buoyancy force
  • particlesQGDFOam - solver for compressible viscous perfect gas flows in a wide Mach number range with particles - from 0 to infinity
  • particlesQHDFoam - solver for incompressible viscous fluid flows with buoyancy force with particles
  • SRFQHDFoam - solver for incompressible viscous fluid flows in rotating frame of reference with buoyancy force
  • QHDDyMFoam - solver for incompressible viscous fluid flows in domains with deforming boundary and with buoyancy force
  • interQHDFoam - solver for incompressible 2-phase viscous fluid flows with buoyancy force and surface tension
  • reactingLagrangianQGDFoam - solver for reacting multicomponent compressible viscous perfect gas flows in a wide Mach number range with particles - from 0 to infinity
  • scalarTransportQHDFoam - solver for scalar transport equation to demonstrate the very basics of QGD/QHD equations principles

Generally speaking, QGD/QHD framework offers an alternative to PISO/SIMPLE and Riemann-solvers approach to simulate various flow phenomena on unstructured grids. And sometimes it could be superior comparing to mentioned techniques.

The framework could be downloaded HERE: https://github.com/unicfdlab/QGDsolver

The presentation covering some theory and basics of the implemeted approach could be downloaded HERE: https://github.com/unicfdlab/QGDsolver/blob/master/qgd-framework-2020-final.pdf

Please, do not hesitate to ask for assistance on how to setup the case or on how to derive new equations for your problem using regularized hydrodynamic approach
