Quite often I hear warnings about "unacceptable" aspect ratios, claims that they ruin simulations, and debate on when stretching is acceptable versus dangerous. The point of this series of posts is to demystify popular myths, help you understand what is happening...
Mesh generation is one of the most critical steps in any CFD workflow. Whether you are running aerodynamic studies, thermal simulations, or complex multiphase analyses, the quality of your mesh directly affects the accuracy, stability, and speed of your results. Two...
The latest CF‑MESH+ 5.6 release introduces important improvements designed to enhance mesh quality and visual clarity. New Feature Implemented a procedure for removing excessive layers while preserving the required first‑layer thickness, ensuring more...
Which solvers and mesh export formats are compatible with CF-MESH+? CF-MESH+ is a solver agnostic software and it is compatible with various other solvers, not just certain forks of OpenFOAM. However, we do understand the possible confusion and misunderstanding, that...
Introduction With CF-MESH+ 5.5, we focused on a problem that has become increasingly important as CFD models have grown in complexity. In the past, meshing often started from relatively clean and well-prepared geometry. Today, CFD workflows increasingly rely on large...
We are pleased to announce the release of cfMesh 1.2, a major update that introduces an integrated graphical user interface (GUI), designed to simplify and accelerate meshing workflows for OpenFOAM users. Additionally, existing command‑line operations continue to...
This is a step-by-step installation tutorial for trial version of CF-MES+, for all the users in trial period. It also contains tips and tricks for troubleshooting in case you have some difficulties with your installation. For successful installation, ensure you follow...
Introduction The main goal of this post is to give you the best meshing practices for high-quality CFD simulations, regarding geometry preparation, cell sizing techniques and boundary layer generation. You’ve probably heard the phrase: "Garbage in – garbage out." This...
Quite often, I hear complaints about non-orthogonality, the required number of non-orthogonality correctors to achieve convergence, and how it is worthless even trying to run a solver on a mesh, etc. The point of this series of posts is to give you an overview of the...
Introduction In Computational Fluid Dynamics (CFD), maintaining mesh quality is crucial for achieving convergence and accuracy. A common issue arises when dealing with acute feature edges—regions where two parts of the surface meet at sharp angles. These edges...
