Upstream CFD

Upstream CFD is a German specialist engineering consultancy founded in January 2019 and headquartered in Berlin. The company focuses on high-fidelity Computational Fluid Dynamics (CFD) and Computational Aeroacoustics (CAA), helping industrial teams solve demanding fluid-dynamics and noise problems. Its core team has worked together for over a decade and brings more than 15 years of advanced CFD/CAA experience with OpenFOAM, the open-source simulation toolbox. The firm describes itself as "Open. Trusted. Proven." and positions its work around open collaboration, rigorous delivery, and contribution to the OpenFOAM community. The company offers a focused range of services rather than a packaged software product. These include end-to-end CFD and CAA consulting — from CAD geometry to actionable engineering insight — as well as tailored method development and optimisation for clients' in-house simulation workflows, high-performance computing (HPC) support and cluster optimisation, third-party integrations and joint product development, and automated CFD workflows for machine learning that can be deployed in the cloud to generate high-fidelity datasets at scale. A notable offering is an "Enhanced OpenFOAM Methods" subscription, which gives access to innovative, validated methods that are synchronised annually with the official openfoam.com release. Upstream CFD serves clients ranging from large OEMs to agile SMEs. Its stated industry focus areas include aerospace, automotive, atmospheric flow, motorsport, process industries, and wind energy. The company's technical specialisms span high-fidelity turbulence modelling, source-resolving aeroacoustics, numerical methods, and high-performance computing. Public materials reference collaboration with major industrial players such as Rolls-Royce, whose geometry is credited in an aero-engine nozzle mixing simulation. The firm's mission is to enable the deployment of high-fidelity CFD in industrial design processes, providing a sustainable platform for delivering specialist expertise on challenging applications. Its team reports 105 unique publications and 1,434 unique citations, reflecting a strong research and development background. Upstream CFD remains a privately held company and continues to operate as an active specialist consultancy in the German and international simulation market.

Upstream CFD was founded in January 2019 by a team of four experts in Computational Fluid Dynamics (CFD) and Computational Aeroacoustics (CAA). The founders had already worked together for over a decade, and the core team brought more than 15 years of advanced CFD/CAA experience with OpenFOAM. The company is headquartered in Berlin, Germany. From the outset, the firm's mission was to enable the deployment of high-fidelity CFD in industrial design processes. Rather than selling a packaged software product, Upstream CFD built its business around specialist services: end-to-end CFD and CAA consulting, tailored method development and optimisation, HPC support and cluster optimisation, third-party integrations and joint product development, and automated CFD workflows for machine learning. A distinctive offering, the Enhanced OpenFOAM Methods subscription, provides access to innovative, validated methods that are synchronised annually with the official openfoam.com release. The company serves clients ranging from large OEMs to agile SMEs, applying its expertise across aerospace, automotive, atmospheric flow, motorsport, process industries, and wind energy. Its technical specialisms include high-fidelity turbulence modelling, source-resolving aeroacoustics, numerical methods, and high-performance computing. Public materials reference collaboration with major industrial players such as Rolls-Royce, whose geometry is credited in an aero-engine nozzle mixing simulation.
