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 the development branch based on OpenFOAM 7 from has been renamed a new branch was added to track developments […]

New branch structure

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

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 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) Ubuntu Linux via pre-packaged OpenFOAM 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

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 […]
