The OpenQBMM repository at GitHub has been reorganized as follows: the master branch is now based on OpenFOAM v1912 instead than OpenFOAM 7 to facilitate synchronization with the sub-module in OpenFOAM from www.openfoam.com the development branch based on OpenFOAM 7 from http://openfoam.org has been renamed development-openfoam.org a new branch development-openfoam.com was added to track developments […]
Announcements
We prepared a patch release to group together bug fixes, particularly regarding the case setup and moment initialization of polydisperseBubbleFoam. No changes impacting user input were made. For a detailed list of changes with respect to OpenQBMM 4.0.0, please refer to the list of commits following no b78a799e8f66481f9c84d63733f513ce57602470 In case you experience issues, please open […]
OpenQBMM 5.0.1 for OpenFOAM 7 is now available
Our article on the zeta realizable scheme for moment transport on R+ support “A second-order realizable scheme for moment advection on unstructured grids”, written in collaboration with EM2C-CentraleSupelec-UP Saclay was accepted and can be found at https://doi.org/10.1016/j.cpc.2019.106993. The pre=print is available on ResearchGate.

We are pleased to release OpenQBMM 5.0.0 for OpenFOAM 7. Notable changes in this release: A new size-velocity quadrature algorithm has been implemented relying on the hyperbolic conditional quadrature method of moments (HyCQMOM). This approach allows the description of particulate flows over a wide range of volume fractions, incorporating the effect of size distribution. The […]
OpenQBMM 5.0.0 for OpenFOAM 7 is now available
The new repository for OpenQBMM at the OpenFOAM Foundation is now live and can be found at https://github.com/OpenFOAM/OpenQBMM. Certain the benefits of working with the OpenFOAM Foundation will be significant for the community, I take this opportunity to summarize the project status and the steps forward. OpenQBMM is the joint work of myself (Alberto Passalacqua), Prof. […]
Contributing OpenQBMM to the OpenFOAM Foundation
We are pleased to release OpenQBMM 4.0.0 for OpenFOAM 6.x. This release includes several new developments and improvements to existing algorithms to improve their robustness. Notably: A new algorithm was implemented in the poly-disperse gas-liquid solver to remove inconsistencies between the transported moments and the two-fluid model used to solve for the mean flow. The […]
OpenQBMM 4.0.0 for OpenFOAM 6.x is now available
We have made the decision of basing our development branch on the stable version of OpenFOAM, rather than OpenFOAM-dev. This reduces the amount of work required to constantly adapt the OpenQBMM code base following the frequent changes to OpenFOAM-dev. It also simplifies the process of verification and validation of our code base, and helps users […]
Changes to development branch
We have updated the installation instructions of OpenQBMM, providing guidance on how to use it on the following platforms: Windows 10 (via Windows Subsystem for Linux) Other Linux distributions, building OpenFOAM from source In case you experience difficulties following these instructions, please report them on the issue tracker.
Updated installation instructions
We are pleaded to announce the release of OpenQBMM 3.0.0. Major changes are summarized below: Multiphase solver polydisperseBubbleFoam for gas-liquid systems based on the solution of a generalized population balance equation for a joint size-velocity NDF (Contributed by Jeffrey Heylmun). The computational model allows each bubble size to have its own velocity (polycelerity), and relies […]
OpenQBMM 3.0.0 released
We are happy to welcome Alessio Domenico Lavino, from the Politecnico di Torino, in our research group. Alessio is joining us for a six-month stay to collaborate on OpenQBMM applied to mixing and population balance equations.

The OpenQBMM live distribution provides rapid access to OpenQBMM, without requiring to build the per-requisites of the code, and, eventually, without installing a Linux distribution. It is ideal for learning about OpenQBMM, and for training purposes. Several formats are available, as illustrated in the dedicated page. The images are created with SUSE Studio, and are […]
OpenQBMM live distribution
OpenQBMM 2.0.0 is now available! A list of the major changes follows. A general framework for the solution of evolution equations involving a distribution function was implemented (univariatePDFTransportModel). Turbulent mixing models: a new solver, mixingTransportFoam, is provided to solve turbulent mixing models using velocity fields obtained from RANS flows solvers. The following mixing models are […]
