OpenFOAM (Open Field Operation And Manipulation)[8] is a C++ toolbox for the development of customized numerical solvers, and pre-/post-processing utilities for the solution of continuum mechanics problems, most prominently including computational fluid dynamics (CFD).

From this initiation to the founding of a company called Nabla Ltd, (predominantly) Henry Weller and Hrvoje Jasak carried out the basic development of the software for almost a decade.

[13] At the same time, Hrvoje Jasak founded the consulting company Wikki Ltd[14] and maintained a fork of OpenFOAM called openfoam-extend, later renamed to foam-extend.

[19] On 3 September 2024, Cristel de Rouvray, CEO of ESI Group officially resigned as Founder Member and director of The OpenFOAM Foundation Limited.

The organisation composition of the initial committee involved members from OpenCFD Ltd., ESI Group, Volkswagen, General Motors, FM Global, TotalSim Ltd., TU Darmstadt, and Wikki Ltd.[23] In addition, nine technical committees were established in the following areas: Documentation, high performance computing, meshing, multiphase, numerics, optimisation, turbulence, marine applications, and nuclear applications with the members from the organisations of OpenCFD Ltd., CINECA, University of Zagreb, TU Darmstadt, National Technical University of Athens, Upstream CFD GmbH, University of Michigan, and EPFL.
