There are many other ways of using OpenFOAM® for Windows, depending on your previous experiences, preferred applications and other circumstances. 5/9/2017 12/16/2019 9/18/2014 Using OpenFOAM, a blockMesh was designed that simply outlined the NACA 0015 foil inside a 3‐D block. However, this first step that I’ve taken is only a pseudo 3‐D case; as the 3rd dimension (z axis) was just given constant values. This is shown using paraView in Figure 1: using paraView to view the blockMesh, a viewing tool ofOpenFoam.

This post provides a mesh for NACA-4digits airfoils using blockMesh. It is a generalized piece of code where you can define the 4-digits and angle of attack inside the script to produce the desired mesh for your case. blockMesh is a built-in mesher in OpenFOAM® . Jun 15, 2018 · BlockMesh will decompose the domain geometry into a set of one or more 3-D, hexahedral blocks. Each block of the geometry is defined by 8 vertices , one at each corner of a hexahedron. Edges of the blocks can be straight lines, arcs or splines .
