If you are just starting to explore the world of meshing and stumbled upon cfMesh and CF-MESH+, you are probably wondering what is the difference between them. Briefly said, cfMesh is open-source and CF-MESH+ is commercial software. Besides the obvious, free vs. paid,...
Introduction CFD engineers often have to work with geometries that were not created by professionals in the field. This situation then results in the handling of imperfect geometries, presenting challenges in the simulation process. The most common problems occurring...
This is a step-by-step tutorial for CF-MESH+ installation, for all the first-time users. It also contains tips and tricks for troubleshooting in case you have some difficulties with your installation. Licensing software CF-MESH+ uses Wibu System’s Code Meter Control...
CFD meshing software price is an important factor when deciding on purchasing the software. In this article, I will try to explain how it is formed, what exactly you pay, and why is meshing worth your money. All of us working on the CFD meshing software have heard the...
Quite often I hear complaints about the required number of non-orthogonality correctors to achieve convergence, and how it’s 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 popular myths and to...
by Dr. Rober Keser I have been using cfMesh for more than seven years now, and it had a tremendous impact on my CFD workflow from the very beginning. I started using the open-source cfMesh for grid creation for various assignments during my master’s degree and I...
Quite often I hear complaints about skewness, and how it’s 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 popular myths and to help you understand what’s going on in your Finite-Volume CFD code...
Quite often I hear complaints about non-orthogonality and skewness, and how it’s 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 popular myths and to help you understand what’s going on in your...
1. Introduction Computational Fluid Dynamics has undergone rapid development in the last two decades. The problems that can be solved with it range from simple laminar flows to very complicated multi-phase flows including heat exchange. CF-MESH+ multi-domain feature...
Introduction The outer boundary layer is a very useful option in our boundary layer library. Mostly it is used in aerodynamic and heat transfer applications, where a fine boundary layer near the wall is desired. Its role is to provide a smooth transition between the...
