cfMesh is an open-source library for volume mesh generation based on OpenFOAM. It implements various meshing workflows for volume mesh generation needed for CFD simulations with OpenFOAM. It is already a part of foam-extend, OpenFOAM for Windows, Caelus and OpenFOAM+ released by ESI. This repository is intended for contribution and collaborative development. If you have a new meshing algorithm or interested in contributing to cfMesh, do not hesitate to contact us. Please note that this code is not the same as CF-MESH+, which is a commercial product offered by Creative Fields Holding.

The foam-extend project is a fork of the OpenFOAM® open source library for Computational Fluid Dynamics (CFD). The goal of this project is to integrate community contributions to the foam-extend CFD simulation toolbox. It is an open project welcoming and integrating contributions from all users and developers.

flow5 is an open-source aerodynamic simulation application designed for preliminary analysis of wings, aircraft, hydrofoils, and sails. As the successor to XFLR5, it combines potential flow solvers with integrated preprocessing and postprocessing tools. Engineers can construct aerodynamic geometries and evaluate their performance under different flow conditions. Its XFoil integration supports airfoil generation and two-dimensional polar calculations. Three-dimensional aircraft analysis includes viscous drag estimation and aerodynamic polar generation. The software supports importing geometry from STL, STEP, and XML files, including complex fuselage shapes. Automated calculations are available through a programming API with batch processing capabilities. flow5 emphasizes efficient modeling and reliable preliminary design evaluation.

FEATool Multiphysics (https://www.featool.com) is a fully integrated toolbox for computer aided engineering CAE, finite element analysis & fluid dynamics simulations. With a very easy-to-use GUI, anyone is now able to quickly set up and perform large scale dynamical and complex engineering physics simulations, with coupled fluid flow, heat transfer, structural mechanics, chemical transport, and electromagnetics effects, without having to learn complex programming. In addition to built-in CAD and pre/post-processing, automatic mesh generation, and multi-physics solvers, FEATool also seamlessly integrates the state-of-the-art OpenFOAM [1], SU2, and FEniCS CFD and FEA solvers. Moreover, native itegration with MATLAB and Python allows advanced simulation scripts and programmatic use cases such as in AI and machine learning [2].
