Boundary and initial conditions with codeStream in OpenFOAM Hello everybody! For new OpenFOAM users, I’d like to talk here about one of the simple ways of customizing boundary conditions and initial conditions. Let’s have a look at this! 🙂 BC & IC in OpenFOAM : usual way of proceeding Basically, in OpenFOAM, boundary and initial […]

PolyDualMesh, a useful OpenFOAM utility Hi everybody! In our category Tips & Tricks for CFD, I propose in this little article to describe an OpenFOAM functionality named polyDualMesh. So let’s see what is this tool 🙂. A little reminder : what is a dual mesh? Let be a given primal n-dimension mesh named M. Its
Comparison of wind pressure coefficients on a cube between experimental results and some CFD approaches with code_saturne Abstract This article is an investigation about the CFD modeling of strain effects generated by wind on buildings. This analysis has been done with the open- source software code_saturne[1] with which several turbulence models have been tested. The

Meshing : a crucial step in CFD In the series of articles concerning the backstage of my job, I offer you today a short description of a particularly important step in CFD (in any case, when using software based on the finite volume method) : the mesh. Some generalities Mesh definition In CFD (and in
Dimensionless numbers : a basic tool for the CFD engineer Reynolds, Mach, Prandtl numbers… In fluid mechanics, it is very common to come across some of them, it is even probably impossible not to. Used wisely, they represent a real asset for modeling a problem, especially in the context of CFD. In this article, I
