Your organisation has an expert in CFD with OpenFOAM. They deliver critical results to problems no one else can solve. They have worked there as long as you can remember. Then one day they announce they are leaving and years of experience and know-how walks out of the door. “That-person-left syndrome”, as we call it, is a failure in maintenance which CFD Direct can help with. We provide development, support, training and cloud services to limit the impact of that-person-left syndrome, building a sustainable CFD capability for our customers with OpenFOAM.
In Year 4 of CFD Direct, we developed new functionality in OpenFOAM and maintained critical components of the code base, reducing the number of unresolved issues by by 17%. We managed the OpenFOAM Foundation: promoting sustainable development, releasing OpenFOAM v6, packaging OpenFOAM-dev and publishing websites and documentation. We contributed 1383 man-hours of unfunded work in-kind to OpenFOAM, including organising and presenting at the OpenFOAM Open Day. We delivered 60 days of OpenFOAM Training, and provided low-cost cloud CFD with CFD Direct From the Cloud™, running 1.3 million core-hrs.
OpenFOAM sustainability involves developing software that meets critical needs of users, through a balance of resources, technology, investment and institutional support. The critical needs are availability, usability, robustness and extensibility. The critical work required to meet those needs are publishing, repair and redesign. Employers rarely allocate time to individuals to contribute critical work, so it is generally left to “career maintainers” at CFD Direct. With limited funding, decisions about the critical work are made by those who fund and/or contribute the work, via The OpenFOAM Hub.
In Year 3 of CFD Direct, we developed new functionality in OpenFOAM and maintained critical components of the code base, reducing the number of unresolved issues by 45%. We managed the OpenFOAM Foundation: promoting sustainable development, releasing OpenFOAM v5, packaging OpenFOAM-dev and publishing websites and documentation. We delivered 60 days of OpenFOAM Training, introducing our new “hybrid” classroom-virtual courses to host participants in person and remotely. We launched the new Cloud CFD course to teach inexpensive, secure, efficient CFD with CFD Direct From the Cloud™.
OpenFOAM is free, open source software for computational fluid dynamics (CFD). At the heart of OpenFOAM is a development kit (“SDK”), providing software and tools to build CFD applications, enabling users to customise their CFD, quickly and conveniently. CFD Direct includes OpenFOAM developers who maintain the SDK. We manage an environment for sustainable OpenFOAM development that involves: early public code release with rapid-turnaround user feedback; a network of developers, funding companies and users; and, co-ordinated code integration and maintenance.
During Year 2, CFD Direct made over 1000 code commits to the public development line of OpenFOAM, making us by far the largest contributor of code to OpenFOAM. We produced the major new version 4.0 release of OpenFOAM and the minor update version 4.1 release. We transformed OpenFOAM-dev into stable software of “always-releasable” quality and package it weekly for Ubuntu. Ubuntu packs can now be installed directly on Windows 10 and we also provide “containerized” versions, hosted on Docker Hub, accompanied by launch scripts for easy installation of OpenFOAM on Linux and macOS.
