Best Free CFD Software of 2024

SimScale, a web-based cloud application, plays an important role in simulation software for many industries. The platform supports Computational Fluid Dynamics, Finite Element Analysis (FEA), as well as Thermal Simulation. It also provides 3D simulation, continuous modeling, motion & dynamic modelling.

SimFlow is a desktop Computational Fluid Dynamics analysis software for Windows OS and Linux OS. It is based upon OpenFOAM libraries and acts as an OpenFOAM GUI. It is a professional CAE package that engineers can use to create 3D simulations. SimFlow is a powerful CFD software that can be used for all purposes. SimFlow combines the intuitive graphical user interface of OpenFOAM®, with the benefits of the open-source OpenFOAM®. SimFlow is free to download and you can use it in an evaluation mode to solve some of the most difficult problems that you face as an engineer or scientist. Perhaps you use CFD software every day or just want to get started on your adventure. SimFlow is a powerful fluid simulation software that allows you to rediscover CFD without any time limits.

OpenFOAM is a free and open-source CFD program that was developed by OpenCFD Ltd. It has been in use since 2004. It is used by many people from both academic and commercial engineering and science fields. OpenFOAM offers a wide range of features that can solve complex fluid flows, including those involving chemical reactions, heat transfer, turbulence, and turbulence, as well as acoustics and solid mechanics. OpenFOAM is professionally updated every six months to include customer-sponsored development and contributions from the community. It is independently tested by ESI OpenCFD's application experts, development partners, and selected customers. It is supported by ESI’s global infrastructure, values, and commitment. The basis of quality assurance is rigorous testing. The code evaluation, verification, and validation process includes several hundred daily unit test runs, a medium-sized test run on a weekly basis, as well as a large industry-based test run.
