Fellow CFD enthusiasts,



A while ago we have shared our new model DLBFoam (https://arxiv.org/abs/2011.07978), which introduces dynamic load balancing to the solution of finite-rate chemistry in OpenFOAM to speedup reactive flow simulations. We now introduce DLBFoam v1.1, which introduces new features such as a fully analytical Jacobian, and improved ODE routines for even faster and more accurate reactive flow simulations. And it is completely open source! We report computational speedup up to a factor of 250 for reactive LES simulations. If you are dealing with finite-rate chemistry in OpenFOAM I am sure that you would find our model extremely useful.



Preprint: https://arxiv.org/abs/2105.12070
